There are many different types of problems that can be solved using the Chemkin subroutines. Driver programs (programs that direct the subroutines and control the input/output files) have been written for the following types of problems:1. Adiabatic flame temperatures.2. Equilibrium concentrations for a gas mixtures.3. Species mole fractions as a function of time in laminar, steady state, premixed flames when temperature profile in known.4. Flame speed, species mole fractions and temperature profile as a function of time in laminar, steady-state, premixed flames.5. Mole fractions and temperature of product stream from a perfectly stirred reactor.6. Determination of transport properties of gas mixtures as a function of composition, temperature and pressure.This is just a small sampling of the numerous driver programs that have been written. The number and type of computer programs which incorporate Chemkin subroutines are constantly increaseing.To use these programs, the user must modify several input files. As will be explained in detail below, each of the input files is in a Unix-shell file and the user will only need to modify the shell file. In order for the subroutines to work, the user must tell Chemkin about the gas mixture and the gas phase reactions. This is done in the file named mech . The user must name each of the elements and each of the species which are in the gas mixture. The user must also enter the elementary steps of the chemical reactions being considered with their respective Arrhenius rate coefficients for the equation: k = AT β exp ER T ⎛ ⎝ ⎫ ⎭ ⎪ (1)The user must also specify the problem by modifying the inp file. This file generally contains information such as initial temperature of the gas mixture, mole fractions of thereactants, and initial pressure. Depending of the program and the nature of the problem, the user will need to include other keywords which control the program. As these are specific toeach of the programs, they will be discussed separately below. Once the inp and the mech files have been properly modified, the program can be run by executing the shell file.For each of the types of problems discussed here, the application code has already been written. The user must only supply the reaction description and the application input. The application input varies from application to application and each will be discussed individually below. The Chemkin applications have been setup and modified to run the HP workstations called the STATES located in room 308 CB. An introduction to these machines will be discussed before the discussion of the applications.Introduction to the HP Work StationsThe HP work stations are powerful computers which operate much faster than the typical PCs. (Some of these programs would require a few days to run on a PC or MAC). All of the STATES are large enough that multiple users can be logged onto the same state.For example, if you sit down at either the TEXAS or the DALLAS terminal, you will be automatically logged into the TEXAS computer. It is possible to login to UTAH from TEXAS or from a PC or Macintosh via TELNET (a communication software package) or by using the command rlogin state from another workstation, but the graphical interface will not be available.These machines use HP-UNIX for an operating system which incorporates both text and graphical interfaces. When you sit down at one of the terminals, if the screen is blank, move the mouse. The login screen will appear and ask for your user's name and password. After you enter both of these correctly, the screen will be blank except for a border and a tool bar.The Tool BarMail- If you have new or unread E-mail, this button will show a couple of envelopes. Press this button and a listing the mail stored in your mail box will appear. You can use this program to read and send mail.CPU Load- This figure shows the load on that state’s CPU. As the load increases th e area plot increases. Horizontal lines mean that the scale on the original screen had to be reduced. If the computer has more than 3 or 4 horizontal lines it might be wise to find another computer that does not have quite the work load.One, Two, Three, Four, Five, Six- These are multiple screens from which you can access your files. If the first screen (One) gets too cluttered with windows, you can switch back and forth between the other screens with these buttons.Printer- Text files can be sent to the laser printer in the next room by clicking the file in the file manager screen with the middle button on the mouse and then dragging the file to this button. Clicking the left mouse button while the mouse is on the printer button will display the printer status.Text Editor- This button looks like pencil on a piece of paper. When this button is pressed, a window containing the text editor is opened. This editor behaves much like the MS-DOS text editor or Edit on the Macintosh.X-Term- Text user interface. When you press this button, a screen will pop up with a cursor. From this screen, the user can enter commands to copy, delete, rename and run various files. It is similar to a DOS screen on a PC. The commands are discussed below.Style Manager- The attributes (colors, background, etc.) of the graphical interface can be changed using the options under this button.Rename Workspace- Allows you to give names to the One, Two, Three, Four, Five, Six screens discussed above.? - This is the help button which contains a more detailed explanation of the HP work station environment.File Manager- This button (looks like a file cabinet) puts a window on the screen which displays all the files in the current directory. If you double-click on a text file in this window, the text editor will pop up with the contents of the file.Trash- Drag files that you want to erase from your directories on to this button and they will be erased when you logout.Exit - Press this button to logout. The computer will then ask for conformation.Essential UNIX CommandsIn this section, only the most essential UNIX commands will be presented. This presentation is not intended to be detailed but should be sufficient to survive in HP-UNIX. Other commands and further detail can be found in the books found in the computer laboratory. Several of the commands presented here can also be done using the graphical interface although I have found the text interface to have more options and be more useful. The information for the different commands will be described in terms of function and format or will be presented in a tutorial format.To begin, press the X-Term text interface button with the left-hand button on the mouse. If you were logged-on to TEXAS, a screen would pop-up with the prompt:texas$HelpHP-UNIX has an on-line help program which has a very detailed description of the use and options of the UNIX commands. To access the help program type:man command [Enter]Where command would be the name of the command for which you had a question. For example, if you typed:man pwd [Enter]a help screen will pop up and describe the pwd command. To scroll down in help use the space bar and to exit help press q.DirectoriesFiles can be stored in tree-like directories. That is, any directory can have sub-directories. To find out which directory path you are in, type pwd [Enter]. The p rintw orking d irectory command will show you the absolute path name of the working directory. Whenever you start a new text interface, you will automatically be placed in your main directory. The output for the pwd command should be:cheme/usernameAll your files should be kept within this directory or sub-directories of username. To see what files or sub-directories you have in this directory type ls [Enter] for List files. The command ls -l (l is a lowercase L) will provide more information about the files and sub-directories.To make a sub-directory use the mkdir directoryname command. For example at the prompt, type mkdir junk [Enter].Now type ls to see the directory that you created.To move down to that directory, type cd junk [Enter]. The c hange d irectory command can be used to move up and down in the directory tree. To see in which directory you are working, type pwd [Enter]. The result should read:cheme/username/junkNow, to move back to your main directory, use the move-up- one-directory command, cd .. [Enter]. The two periods mean the parent directory or the directory directly above the current directory. Type pwd [Enter] to make sure you are now in your main directory.To remove the junk directory, type rmdir junk [Enter]. In order to remove a directory, the directory must be empty of all files and sub-directories.Note: Every time you call up a text interface screen, it will automatically open to your main directory. In order to access any of your programs or files in other directories, you must first change to the directory in which the files are located.FilesThere are three basic types of files used by Chemkin. Text files can be edited by the text editor. They cannot be executed unless they are a program source code and are first compiled. Shell files are denoted with the .sh extension are similar to .bat file in MS-DOS. They are text files which can be executed and will direct the compilation of FORTRAN codes, direct a sequence of program calls, and direct file input and file output. They can be edited by the text editor and executed by typing:sh shellname.shIf the .sh file is already in the execute attribute (see File...Properties in graphical interface File Manager) then the shell file can be executed by:shellname.shFor the Chemkin programs for which shell files have been written, you will not need to do any programming in FORTRAN but will need to modify the shell files.The third type of file is an non-text executable file. These files are created by compilers and cannot be edited by a simple text editor. Since all the compilation of the FORTRAN source code will be directed by the shell files, you do not need to directly run these programs.There are several commands which are very useful in manipulating files. To make a copy of a file use the cp command. When using the format cp file1 file2, the computer will make a copy of file1 and call it file2. This will not destroy file1, but will destroy any old copies of file2. To copy a file into another directoryuse the format cp file1 path/directoryname. This will place a second copy of file1 into directoryname. To copy all the files in one directory to another use cp *path/directoryname.To move or rename files and directories use the mv command. This has the same format as the cp command except, the original file is destroyed. For example, if you typed mv file1 file2, file2 would be a copy of file1 and file1 would be erased.To erase a file using the text screen, use rm filename. If you use rm -i filename, the computer will request conformation before a file is deleted.Other than using the text editor, text files can be viewed using the more command. (Format more filename). This command will display the contents of a text file to the screen and will pause before scrolling. Because the more command only allows you to scroll down, it is often better to use the text editor to view files.Other useful commands and tricks in UnixTo change your password, type passwd at the prompt.To run a program in the background add an “&” to th e end of the file name. When a program is running in background, you can log-off the system and the program will keep going. To execute the premixed flame shell in the background, you would type:sh premix.sh &If the program is already running but not in the background, press [ctrl]-[z] to pause the program, and type bg at the prompt to put the program in the background.Once a file is running in the background, you can follow its progress by a number of ways. It is often necessary to follow some of the Chemkin programs, because they tend to crash if the initial guesses are far from the true solution. To see if it is still running type jobs -l (lower case L) at the prompt. This will list all the programs currently being executed from that window. To list all the programs currently being executed on that computer type ps -e. (Sometimes this list can be long so to control the screen output use ps -e | more. The | will pipe the output from the ps command through the more command.) Both the ps and the jobs commands will list a number associated each program in execution. This number can be used to stop the execution of the program with the kill command. For example, if you want to kill program number 1, type kill %1.The contents of the output file can be followed as the file is being generated by using the tail command. For example, to follow the output from the premixed flame shell program, type tail -f premix.out. To exit the tail command press [ctrl]-[c]. When shell files are executed, their progress is written to the file .log. To follow the .log file, use tail -f .log.If your program stops running but the output file is empty, look at the files ckout and tpout(in the text editor) and they will tell you if there are any errors in your mech or inp files.If your workstation should freeze, press [shift]-[ctrl]-[reset]. This will reset your computer. These buttons are on the left side of the keyboard. Any files that were not previously saved will probably be lost.To print files, you can either use the text editor or use the lp command. The format is lp filename. This will print two pages per piece of paper. This command and the printing from the text editor will truncate any line which is over 80 columns. To print files that are wider than 80 columns do the following:1. psf -1sc 150 <filename>junk2. lp junkBe careful when you are printing some of the .out files because they can be quite long and can contain a lot of unnecessary information. In most cases it will be better to first erase the unwanted information by using the text editor and then printing the file.Also be careful not to send non-text files to the printer or hundreds of pages could be wasted.From certain STATES or terminals a file cannot be directly printed. If your file does not print after sending it to the printer you will need to rlogin on ALASKA and print from that machine. Do the following on a X-term window of any machine in the room:1. rlogin alaska2. cd to directory where your file is located. (You can use pwd find out in which directory you are located.3. lp filename4. logoutThere are many other commands available in UNIX. Please refer to a manual to learn other commands.Equilibrium Calculations using Chemkin-IIThe Chemkin equilibrium software is easy to use but is not as powerful as other equilibrium programs like the NASA-LEWIS code or the EDCONV code. The latter two programs, will search their data bases to determine what species should be considered in an equilibrium calculation. The Chemkin code requires that the user input all the species which are to be considered. In the example of methane combustion in air, NO and NO2 formation will not be considered unless those two species are entered into the program. CO will not even be considered unless it is input into the program.Instructions for using the Chemkin Equilibrium Solver1. Login to an HP workstation.2. Open the Text Editor.3. Under the File pull-down menu, select Open...4. Open equil.sh (you may need to change directories)5. Scroll down to the line below “cat << EOF > mech”.6. After the word “ELEMENTS” enter the symbols of every elem ent that will be in any species that should be considered in the equilibrium calculation. Isotopes can be considered if their atomic weight follows their symbol in slashes “/”. Lines beginning with an exclamation mark are ignored. Conclude the elements section with the word “END”. Example:ELEMENTSNH! Define DeuteriumD /2.014/OENDAlso Acceptable is:ELEMENTS N H D /2.014/ O END7. After the word “SPECIES”, enter the symbols of every species that should be considered. The format is similar to the elements section. Example:SPECIES H2 O2 H O OH HO2 N2 N NO ENDIf species which are not contained in the thermodynamic data base need to be considered, check out the manual entitled Chemkin-II: A FORTRAN Chemical Kinetics Package for the Analysis of Gas Phase Chemical Kinetics. This manual will provide more detail on extra features of the Chemkin software package. Thermal dynamic data for numerous hydrocarboncombustion species are available in the correct format for the database in Combustion Chemistry, edited by William C. Gardiner or from the NASA-LEWIS equilibrium code data file.8. Scroll past the driver program to the line: “cat << EOF > inp”9. The shell file generates a file named inp that contains the keyword inputs to specify the problem for the equilibrium program.10. The following keyword inputs are allowed in any order:REAC - Specifics the reactants and their molar quantity or mole fraction. Format: REAC H2 2CONH - Constant enthalpy can be used in conjunction with constant volume or pressure, but not with constant temperature, entropy or internal energy.CONP - Constant pressure can be used with constant temperature, volume, enthalpy or entropy, but not with constant internal energy.CONT - Constant temperature can be used with constant pressure, volume or entropy but not with enthalpy, and constant internal energy.CONV - Constant volume can be used with constant temperature, pressure, internal energy, enthalpy or entropy.CONU - Constant internal energy can be used with constant volume only.CONS - Constant entropy can be used with constant temperature, pressure or volume, not with constant internal energy or enthalpy.CONX - Constant mole fractionCHAP - Chapman-Jouguet- cancels all the above specification except REAC. This keyword causes the detonation-wave velocities to be calculated.TEMP - Required input for the starting temperature in K. Format: TEMP 298TEST - Estimate equilibrium temperature in K.Format: TEST 2500PRES - Starting pressure in atmospheres. Format: PRES 1PEST - Estimate of equilibrium pressure in atmospheres.Format: PEST 1.5CNTN- Tells the computer to look for an additional problem after the keyword END.END - End of keyword input.An example of a input file inp to calculate the equilibrium concentrations of a stoichiometric hydrogen flame in air and a fuel rich hydrogen flame is:REAC H2 2REAC O2 1REAC N2 3.76CONHCONPTEMP 300TEST 2000PRES 1CNTNEND/ This is the second problem.REAC H2 3REAC O2 1REAC N2 3.76END11. If you would like to customize the output file name, you must edit the file name on the second to last line in the shell file.Example:Before:make equile; equile < inp > equil.outAfter:make equile; equile < inp > filename12. Under the File pull-down menu of the text editor, select the Save or Save as.. command.13. Open a text interface window by clicking on the X-term button on the tool bar.14. Change the directory to the directory where the Chemkin files are located using the cd command.15. Run the shell program by typing: sh equil.sh16. When the cursor reappears, the program is completed and the output file can be viewed and printed via the text editor.Example Problems for Chemkin Equilibrium Program1. Calculate the adiabatic flame temperature and equilibrium composition of CO in air with equivalence ratios of 0.5, 1,2. (Do not consider NO x formation). (Feed conditions- 300 K, 1 atm). Consider using the CNTN keyword to save some time.2. Repeat problem 1 but consider NO x formation.3. Repeat problem 2, but make the inlet feed contain 10 percent H2.4. Compare the results from problem 3 with either the EDCONV program or the NASA-LEWIS code. If you forgot a significant species in problem 3 as determined by one of the other two programs, repeat problems 3 and 4 again. What are two reasons for using the Chemkin equilibrium program, if one of the other equilibrium codes is available?Laminar, Pre-mixed, One-dimensioned Flame Calculations“Many practical combustors, such as internal combustion engines, rely on pre-mixed flame propagation. Moreover, burner-stabilized laminar premixed flames are very often used to study chemical kinetics in a combustion environment. Such flames are effectively one-dimensional and can be made very steady, thus facilitating detailed experimental measurements of temperature and species profiles. Also, laminar flame speed is often used to characterize the combustion of various fuel-oxidizer combinations. Therefore, the ability to model chemical kinetics and transport processes in these flames in critical to interpreting flame experiments and to understanding the combustion process itself.” (Kee, 1992)The Chemkin premixed flame code is designed to handle a variety of problems. The calculations involve solving systems of non-linear mass balances, energy equations, and transport relations. There are two major divisions in the types of problems that the premixed code will solve. The burner stabilized problem requires a known mass flow rate, and the temperature profile can either be specified or calculated from energy equations. Often it is better to specify the temperature profile if it can be experimentally determined because heat loses from a flame can be difficult to quantify. Problems where the temperature is specified are relatively easy to solve compared to the second type of problem. The second type of problem involves an adiabatic freely propagating flame. From the input, the flame speed, temperature profile, and concentration profile are calculated. This type of problem is very difficult to converge and solving them requires some skill, experience and a lot of patience. The code is currently configured for a burner diameter of 1.0 cm2.Setting up a Premixed Flame Problem1. Login to an HP workstation.2. Open the Text Editor.3. Under the File pull-down menu, select Open...4. Open premix.sh5. Scroll down to the line below “cat << EOF > mech”.6. After the word “ELEMENTS” enter the symbols of every element that will be in any species that should be considered in the equilibrium calculation. Isotopes can be considered if their atomic weight follows their symbol in slashes “/”. Lines beginning with and exclamation mark are ignored. Conclude the elements section with the word “END”. Example:ELEMENTSNH! Define DeuteriumD /2.014/OENDAlso Acceptable is:ELEMENTS N H D /2.014/ O END7. After the word “SPECIES”, enter the symbols of every species that should be considered. The format is similar to the elements section. Example:SPECIES H2 O2 H O OH HO2 N2 N NO ENDIf species which are not contained in the thermodynamic data base need to be considered, check out the manual entitled Chemkin-II: A FORTRAN Chemical Kinetics Package for the Analysis of Gas Phase Chemical Kinetics. This manual will provide more detail on extra features of the Chemkin software package. Thermodynamic data for numerous hydrocarbon combustion species are available in the correct format for the database in Combustion Chemistry, edited by William C. Gardiner. Transport property data may also need to be added to the transport property data base.a. This section must begin with the word REACTIONS. The default units for the Arrhenius rate coefficients are cal/mole for the activation energy and the units of A are in terms of cm, sec, K, and moles. Equation 1 is shown here again: k = AT β exp ER T ⎛ ⎝ ⎫ ⎭ ⎪ (1)These default units of the activation energy can be changed by adding the words CAL/MOLE, KCAL/MOLE, JOULES/MOLE or KELVINS after the word REACTIONS. The default units for A can be changed by adding MOLECULES so that the units of A are in terms of cm, sec, K, and molecules.b. The information of the reaction is fairly free from format but certainconventions must be observed. At the beginning of the line the reaction mechanism must be symbolically written. No more than 3 molecules can be on either side of the equality. All coefficients of reactants must be integers. A plus sign (+) is used to separate the reactants from the reactants and the products from the products. There are two symbols used to separate the reactants from the products. The equals sign (=) is used to represent a reversible reaction. When this symbol is used, the reverse reaction is considered and calculated using the equilibrium constant. When the symbol => is used, the reaction is assumed to be irreversible and the reverse reaction is not considered. Third body reactions can be considered by using thesymbol M as both a reactant and product. The M species does not need to be declared in the SPECIES section. On both sides of the equation, M must be the last species. The defaultthird body efficiency is one, but this can be modified as shown in the example elementary step. The three Arrhenius coefficients (in order of A, , and E) are on the same line as the reaction and must be separated by at least one space. (Multiple spaces or tabs are acceptable for separating the data on a line.) Exclamation marks (!) signify that information following the ! is to be ignored. An example elementary step is:H + O2 + M = HO2 + M 0.361E18 -0.72 0.0H2O/18.6/ H2/2.86/ N2/1.26/ ! 3rd body efficienciesRefer to the manual, Chemkin-II: A FORTRAN Chemical Kinetics Package for the Analysis of Gas Phase Chemical Kinetics for details on handling photo-chemical reactions, pressure-dependent fall-off reactions and Landau-Teller formulation of rate expressions.c. End the mechanism description with the word END.8. Scroll down to the line: “cat << EOF > inp”9. The shell file generates a file named inp that contains the keyword inputs to specify the problem for the premixed laminar flame program. In the Appendix there are several pages directly from the manual and explain all the possible keyword inputs. Some of the most important keywords will be discussed here.BURN - A required keyword for burner-stabilized flame problems.FREE - Required for adiabatic freely propagating flame. (Note: either BURN or FREE must be specified by not both but this can be changed on continuation (CNTN) or restart (RSTR).)TGIV - For burner-stabilized flames, the species equations will be solved using the user-specified temperature profile.ENRG - The temperature profile will be calculated using the energy equations, but the user must enter initial guesses for a temperature profile using the TEMP keyword. (Note: Either TGIV or ENRG must be specified for BURN type problems.)MOLE or MASS - Used to specify that answers and inputs are in either mole or mass fractions.PRES - Pressure of the flame in atmospheres. Format: PRES 1.0.FLRT - Specified flow rate for burner stabilized flames or initial guess for adiabatic freely propagating flames. Units are in g/cm2-sec. Format: FLRT 0.04.REAC - used to specify initial reactant mole or mass fractions.INTM - used to give the computer initial guesses of intermediate species mole fractions.PROD - used to give the computer initial guesses of product species mole fractions。

chemkin安装成功，总结⼀下经验
真得挺困难的，终于功夫不负有⼼⼈，安装成功了。

chemkin是计算化学反应动⼒学的⼤型软件，现在研究天然⽓发动机，我想⽤它来计算⼀下化学反应的问题，所以想学学他，没想到在安装过程中遇到了很⼤的困难。

⾸先，我的机器上装了windows版本的star-cd ，安装了exceed,还安装了catia，不知道这些软件怎么了，我每次安装chemkin，都觉得安装上了，但是找不到任何.exe执⾏⽂件，桌⾯上也没有快捷⽅式。

整个⼀个空城计。

看来我的电脑是不⾏了，只能在实验室找台机器安装了。

找了⼀台机器，安装了chemkin4.0，这下挺好，⼀下了就安装了，把我⾼兴坏了，可是难题也出现了，license⼀直都不好⽤。

弄得我没有任何办法。

看到⽹上有chemkin4.1，我就下载了，安装在机器上，很容易就安装了，license⼀下就安装上了，但是不好⽤，我详细看了⼀下，终于发现了问题，简单修改⼀下，⼀切都ok了。

1、chemkin 4.0⽹上流⾏的破解license，只能和破解的chemkin配合使⽤，不能和正版的配合⽤。

那样是⾃讨苦吃。

2、破解的license能⽤写字板打开，要把HOSTID=ID=********,替换成HOSTID=****（⾃⼰机器的physcial address)
3、physcial address，可以通过 inpconfig /all 的命令来找到。

CHEMKIN PRO1.首先解压，得到，以存储到F盘中为例，按照路径F:\软件\Reaction.Design.Chemkin.Pro.v15083.WiNNT2K-oDDiTy\Reaction.Design.Chemkin.Pro.v15083.WiNNT2K-oDDiTy\Reaction.Design.Chemkin.Pro.v15083.WiNNT2K-oDDiTy，找到如图1所示的3个文件。

注意该目录下的chemkin15083_pc子文件夹，其中有两个文件夹，即lib 和bin文件夹，另外，在licenses文件夹中，有一个文件reaction.lic。

这三个文件（夹）在后续安装中会用到。

图12.点击安装程序，选择安装文件夹，可以选择安装在C盘或者D盘，期间会提示是否安装ATT Graphviz程序，简便起见，选择同意安装。

然后计算机开始安装CHEMKIN PRO软件，完成之后提示重启计算机，选择重启。

3.重启完计算机之后，如果计算机是Windows 7操作系统，找到安装文件夹，以安装到D盘的Program Files文件夹中为例，按照路径地址打开data文件夹，打开文件OSName_Map.properties，用记事本（打开.txt的程序）打开，找到Windows\ Vista^6.0=WINNT这一行代码，改为Windows\ Vista^6.1=WINNT，保存关闭。

如果是Windows XP系统，不作此修改。

4.打开软件安装文件夹D:\Program Files\Reaction\chemkin15083_pc，注意到其中包括两个子文件夹，分别是bin和lib文件夹，然后用第1步中提到的两个同名文件夹内容，lib和bin，来替换这两个文件夹。

5.将第1步中提到的许可证文件reaction.lic拷到安装文件夹D:\ProgramFiles\Reaction\licenses中。

ChemOffice 15.1有哪些安装步骤化学绘图软件ChemDraw出了最新版ChemOffice 15.1了，其下有三个不同组件，其中ChemDraw15.1 Pro使用范围最广。

当我们下载完软件后就需要对其进行安装，一般按照流程来就没有什么大的问题，但是一些新手用户对一些细节不是很了解，下面我们就来和大家分享一下ChemOffice 15.1有哪些安装步骤？第一步：安装ChemDraw的第一步当然是获取ChemDraw15.1 Pro安装包，为了避免在安装或使用过程中发生莫名其妙的异常情况，建议从ChemDraw中文官网获取正版软件安装包。

当然，这也是为了保障用户的个人利益不受侵害。

第二步：双击安装包，系统会开始解析提取安装包中的内容，整个过程在15秒内完成。

第三步：打开ChemDraw15.1 Pro的安装页面，单击Install Software开始安装教程，除了开始安装软件，用户还可以阅读使用须知、使用手册、版本功能、系统要求以及获取服务支持。

ChemDraw15.1 Pro安装页面温馨提示：如果用户的电脑上安装ChemDraw旧版本或者旧版本插件，会弹出以下提示框，请在安装ChemDraw15.1 Pro前卸载旧版本及插件。

卸载旧版本第四步：进入安装ChemDraw的欢迎页面，点击Next，这里需要注意的是为了成功安装ChemDraw15.1 Pro，程序会暂时禁用防火墙功能，安装结束，防火墙会被重新激活。

暂时禁用防火墙第五步：阅读“用户许可协议”，这是安装所有正规付费软件均有的一个过程，将页面拖拉至最下方，否则进入下一个步骤的按钮灰显，勾选“I accept the terms in this license agreement”选项。

第六步：选择安装方式，默认安装或者自定义安装，根据自己的需要可以更改目标文件夹的位置，然后点击Next。

更改目录文件位置第七步：选择需要安装的插件以及第三方应用程序，比如ChemDraw15.1 Pro、ChemScript、Python。

ChemKin4.0 操作入门安装：运行setup.exe。

然后把carck文件夹中的chemkin.lic文件拷到安装目录下的licenses文件夹中。

一、新算例设置的基本操作1、建立新工程2、设定反应器模型在左侧models面板双击所需反应器模型，如PSR模型，则反应器模型出现在右边的Diagram View面板，下角Update project按钮变成黄色。

当设定好模型后，点击该黄色按钮确定，按键变成灰色，方可进入下一步反应机理设定。

3、设定反应机理在左侧，Open Projects面板，双击Pre-Processing。

进入机理设置界面。

Working Dir 是所有计算结果，包括工程文件的存储位置，自行设定。

点击New Chemistry Set，设定机理文件，必须设定Gas Phase Kinetic File—后缀为.inp；Thermodynamic Data File――后缀为.dat，都通过设定路径来设定。

设好后Save As…，确定，就变成下面的样子，点Run Pre Processor。

运行成功则View Results….变成黑色，Cluster变成黑色，没有跳出任何消息框。

运行成功方可进行计算的初始参数设定。

在cluster中，●properties选求解Gas Energy Equation，●C1表示反应器，在reactor physical properties中设置停留时间、温度、压力、体积、热损失等项。

注意单位。

表面项和传输项设置留待诸位研究设置方法。

在species specific data 中设置反应器中原有的物质组分，要各组分的fraction加起来＝1。

这一项我的计算中不需要设置。

注意，此处设置的温度为牛顿迭代计算的初值，默认条件下等于入流温度。

●R1表示入流。

入流可以有多个，比如我的先进再燃就有5个入流，入流再多也应该没有关系，进去就都一样了，看设置参数的方便而定。
