16th Australasian Fluid Mechanics ConferenceCrown Plaza,Gold Coast,Australia2-7December2007A computational study of the influence of the injection characteristicson micro-turbine combustionC.A.Gonzalez1,K.C.Wong1and S.Armfield11School of Aerospace,Mechanical&Mechatronic EngineeringThe University of Sydney,AUSTRALIAAbstractMicro-turbines have been lately recognized as promising alter-natives for powering unmanned aerial vehicles(UA Vs),hybrid transport and small scale electricity generation.Due to their traditional use in military and recreational applications,a good deal of empirical and general data is available but little technical and scientific information about their behaviour,and in particu-lar about their combustion characteristics can be obtained. Injection is widely recognized as a major controller of the com-bustion process in thermal machines such as diesel engines and gas turbines.In this paper a computational study is undertaken to identify the influence of the injection characteristics on the thermodynamic variables inside a commercial micro-turbine. Large eddy simulation is used for describing the turbulence. Statistical design of experiments is used to evaluate the influ-ence of each factor and their interactions as well as for reduc-ing the amount of simulations.Results indicate that changes in droplet size and injection velocity can improve the conditions at the outlet of the combustor.IntroductionThe micro-turbine industry has grown dramatically in the last decade.This is because new applications for these engines,such as small scale electricity generation,unmanned aerial vehicle propulsion and hybrid transport,have been developed.Micro-turbines,when compared with the state of the art recip-rocating engines,promise better power to weight ratio,more flexibility,lower emissions and the possibility offlying faster and at higher altitudes.However,their fuel efficiency is still low.This is the main reason why they have not found yet a more widespread use in those areas.A further understanding of the behaviour of the engine can yield improvements in their performance.This is the aim of this work,focusing on the com-bustion chamber.The combustion process is a key factor in the operation of the turbine.A better understanding of this process can not only benefit the efficiency of the engine at given conditions but also make it possible to expand the area of operation of the engine. Several studies have been undertaken analysing pressure loss [1],implementing lean combustion for low NOx emissions[2], comparing different configurations[3]and analysing the com-bustion process through computationalfluid dynamic simula-tions[4,5].The injection process plays an important role in the combustion, yet the extent of the influence of the main injection variables, such as droplet diameter,spray diameter and injection veloc-ity on the combustion process of micro turbine engines,using vaporisers at this scale,is still unclear.This paper focuses on the influence of three variables of the injection process on the combustion inside micro turbines using CFD.The initial droplet diameter,the outlet velocity and the straight forward manner,for example by changing the injection pressure or changing the injector type using air blast,simplex or plain orifice atomizers.This paper can serve as a guide to determine if the implementation of more advanced atomizers is useful for micro-turbine combustion.In micro-turbine engines,the optimal condition for a combustor is to have the highest and most homogenious temperature at the outlet with the minimum pressure drop.Given a constant mass flow rate and outlet area,the pressure can be easily related with the velocity at the outlet.In this study,only the velocity and average temperature at the outlet are considered in a high load condition.In the following section,the methodology of the study is thus described.The details of the turbine and combustor,together with the model and mesh details are presentedfirst.The turbu-lence and combustion models are then described,followed by the boundary and operating conditions and a description of the design of experiments and test plan.Results are presented in terms of the temperature and velocityfields.Finally the conclu-sions are detailed.MethodologyTurbine and combustorMesh detailsAs explained by Gonzalez et al[5]Large Eddy Simulation (LES)outperforms Reynolds Average Navier Stokes(RANS) turbulence models for this problem.In particular their results show that LES with wall adapted local eddy viscosity(WALE) sub grid model yields the best results.This is the model that is employed in the present study.Afinite rate model for the simulation of combustion is used. Due to the high chemical complexity of the kerosene,a sur-rogate fuel consisting of80%n-decane and20%toluene is em-ployed for simulating this fuel.The steadyflamelet model[8,9] is utilised together with a reduced mechanism of63species and 167reactions[10].Fuel injection modelSecond order discretisations are used for all equations.The sec-ond order implicit in time approach is employed for the un-steady formulation.Pressure and velocity coupling is carried out via the PISO algorithm.The time step for unsteady cases was2×10−5s.Residual convergence for continuity,velocities, mixture fraction was considered acceptable below10−3,while that of the energy equation was10−5.A high load condition is evaluated in this study.The total air flow is0.22kg/s,the inlet pressure is2.2bar and global air fuel ratio is65[7].The inlet temperature of the air is400K while that of the fuel is300K.A validation study for this case with all the models previously described was performed by Gonzalez et Design of experimentsInj.vel.(m/s)315515100There are several types of response surfaces,they vary mainly on the position and amount of points to be used.In this study the Box-Behnken design,which considers only the points at the edjes of the enclosed cube,was selected as a good compro-mise between accuracy and test reduction [19].The best pre-dictions with this model are in the sphere/ellipse enclosed by these points.This has made it possible to reduce the number of computations from 27possible combinations (considering a parametric study of 3factors at 3levels)to a total number of 14,including the validation point.ResultsTo analyse the combustion process,the mean values of the tem-perature and velocity at the outlet obtained with the steady state solution are used.Surface responses were thus created for these two variables in terms of the drop size,injection velocity and spray angle and their interactions.As explained earlier,the re-sponse surface methodology makes it possible to obtain a poly-nomial equation.In this case the obtained equation represented the data with a R 2of 88%and 84%for the temperature and ve-locity,respectively.The standard error of estimation for each case was 25K and 4m/s.This values in the order of varia-tion of the steady state solution due to turbulence so it can be considered adequate.In Figure 3the pareto plot of the main effects and the second or-der interaction of the droplet size are displayed.The pareto plot for the temperature yields very similar output and is therefore omitted.This plot indicates which factors are not statistically significant.This is done by looking at those factors whose bar is below the statistically significance line.Only these four factors are displayed since all the rest of them (second order interac-tions)have been taken out of the model (through the procedure explained in section )due to their lack of significance.01234Standarized effectDrop size x Drop Inj.Drop +_Figure 3:Standarized effect of the different parameters over the temperature.The first point to notice in this plot is that the spray angle is not significant for the model while the effect of the injection veloc-ity and drop size is bigger than the predicted error.Also,the interactions between the factors are not significant.Thirdly,the effect of both the injection velocity and drop size are negative,showing that an increase of both factors decreases the velocity (or temperature)at the combustor outlet.In figures 4and 5,contour plots of the effect of the drop size and the injection velocity on the outlet temperature and the out-let velocity are displayed.As noted,smaller drop sizes make it possible to get higher temperatures and velocities.This fac-tor shows a quadratic effect on both variables illustrating that a further reductionof the drop size can lead to higher tempera-tures/velocities and that a further increase in the drop size is notgoing to create a very dramatic effect on the performance of the Figure 4:Effect of the drop size and injection velocity on the mean temperature at the outlet of the combustor.Figure 5:Effect of the drop size and injection velocity on the mean velocity at the outlet of the combustor.In Figure 6,the mean temperature at the mid section of the com-bustor is displayed for the two different levels of the drop size at 3m/s and 5deg.As noted,the high temperature region is more properly defined in the 10µm case.In this case,as seen in Figure 7,higher evaporation rates inside or very close to the vaporiser make it possible to achieve a rich and homogenious mixture in the pri-mary and secondary zones.As seen in Figure 8,this makes it possible for this mixture to have a well established flame front when it mixes with the secondary and part of the diffusion air.Bigger droplets evaporate in more distributed locations.There-fore,local stoichiometric mixture fractions (and high temper-ature zones)can be found in a broader area.However,some of the bigger droplets are not able to evaporate and mix com-pletely before or inside the combustor which explains most of the decrease of temperatures.Higher injection velocities lead to lower outlet temperatures and velocities as seen in figures 4and 5.In Figure 9,comparative images of the mean temperature at the mid section of the com-bustor for the two extreme levels of the velocity at 151µm and 5deg.are displayed.It can be noted that substantially lower temperatures are ob-tained inside the combustor when the injection velocity is in-creased.As observed in Figure 10,this is because leaner mix-ture fractions are obtained.The fuel mass source contours of Figure 11indicate that this is due to a more distributed evapo-ration.As noted in this same figure,there is still evaporation at the outlet of the combustor.This means that incomplete com-bustion is taking place,which can explain the overall decrease in temperatures.Figure6:Temperature at the mid-section cut of the combustor

injection velocity and spray angle are3m/s and5deg,respectively. DiscussionIt is noted from this study that most of the evaporation takes place at the outlet of the vaporiser when the droplet diameter is increased to more than100µm.As explained in the fuel injec-tion model section,the validation studies for the fuel injection model have shown that this is a typical initial droplet diameter for plain orifice atomisers such as the one usually installed in this engine.The design of the vaporiser is thus,not optimal.A longer design can make it possible for the evaporation to take place inside the primary zone.Also,the use of air blast atomis-ers can be helpful in this sense.Also,slower velocities make it possible to obtain complete combustion.Most of the injectors rely on an increase in in-jection pressure for decreasing the drop size.As observed in this study,the benefits of decreasing drop size are much higher than the drawback of increasing injection velocities.However,a very rich combustion is obtained when the drop size diameter is decreased.This may lead to very high NOx production.Based on this data,the combustor could be improved by an increase of the primary air and a reduction of the drop size.This could lead to lower mixture fractions,leaner combustions and lower NOx. ConclusionsA CFD analysis of a micro turbine combustor under reactive conditions has been performed.The influence of injection con-ditions was assessed.The results indicate that decreasing the drop size and increasing the injection velocity leads to an over-all increase of outlet temperatures.This is because a more com-plete combustion is achieved.Most of the evaporation takes place at the outlet of the vaporiserFigure9:Temperature at the mid-section cut of the combustor for the3m/s(a)and100m/s(b)cases.The drop size and spray angle are151µm and5deg,respectively.even small sauter mean diameter for plain orifice atomisers,the design of the vaporiser of this combustor has been found to be somewhat short if complete evaporation is desired.A higly premixed rich combustion can be obtained when the drop size diameter is decreased.This may lead to very high NOx production.An increase of the primary air,increasing the vaporiser diameter,together with an increase of length and a reduction of the drop size by means of a more efficient atom-iser can lead to lower mixture fractions,leaner combustions and lower NOx.AcknowledgementsThe authors wish to thank the Conselleria de Empresa,Uni-versidad y Ciencia of the Generalitat Valenciana,Spain,for its support through a post doctoral fellowship.References[1]M.D.Agrawal and S.Bharani.Performance Evaluationof a Reverse-flow Gas Turbine Combustor using Modi-fied Hydraulic Analogy.The institute of Engineers IndiaJournal MC,April2004:34–44,2004.[2]HeonSeok Lee and JeongJung Yoon.The Study onDevelopment of Low NOx Combustor with Lean BurnCharacteristics for20kW class Microturbine.Proceed-ings of ASME Turbo Expo,14–17June,Viena,Austria,2004.[3]R.Tuccillo and paring differentsolutions for the micro-gas turbine combustor.Proceed-Figure10:Mixture fraction at the mid-section cut of the com-bustor for the3m/s(a)and100m/s(b)cases.The drop size and spray angle are151µm and5deg,respectively.[4]Levy,Y.et al Experimental-theoretical study of spraycombustion in the small jet engines.Annual Israeli JetEngine Symposium(AIJES).16November,2006.

Short Term MemoryReports of short-term memory difficulties in Turner syndrome are mixed. Digit span scores are lower than other verbal IQ subtest scores (e.g.: McCauley et al.. 1987; Rovet, 1993) and comparable to those of children with nonverbal learning disabilities (Williams. Richman. &Yarbrough, 1991). However, sentence memory performance is intact (Williams et al., 1991; Mazzocco, 2001). Both verbal and visual short-term memory tasks appear difficult for girls with Turner syndrome, and both difficulties appear to be mitigated by estrogen treatment(Ross, Roeltgen, Feuillan. Kushner, & Cutler. 1998, 2000).Executive FunctionTemple et al. (1996) administered a variety of executive function tasks to girls with or without Turner syndrome. The tasks included word fluency tests with_ phonological constraints (e.g.,name as many words as possible that begin with s. within a time limit) or semantic constraints (e.g., name as many animals as possible); the Wisconsin Card Sorting Task WCST; Heaton.1981); the Tower of London tasK (Shallice. 1982); the Stroop test (Stroop, 1935); and an adaptation of the self-ordered pointing task with either abstract or concrete drawings. (This last task involved pointing to each of six items, one per page all items appear on each page.yet their spatial locations differ on each page.) No group differences were noted on the WCST, a test traditionally used to measure perseverative response patterns and the inability to shift response sets; this result is consistent with earlier reports (Pennington et al.. 1985). There were also no differences on the Tower of London, a task requiring planning for efficient sequential responses toward a goal state. However, girls with Turner syndrome performed more poorly than girls in the comparison group on the word fluency tests. which require an organized search of the lexicon and monitoring of words already named. Also, girls with Turner syndrome were slower during the nonexecutive naming trials of the Stroop (i.e., naming the color of Xs and reading aloud color words printed in black)and showed a significantlystronger Stroop effect on the executive function trial (i.e., naming the ink color of color words printed in colors inconsistent with their meaning, such as the word red printed in green ink).The latter result reflects difficulty inhibitting a prepotent response set. (This finding may appear to contradict the absence of impairment on the WCST but Stroop interference is probably more difficult to inhibit than the response set established in the WCST.) On the self ordered pointing task, girls with Turner syndrome performed as well as the comparison group on the concrete-pictures subtest but were significantly more impaired on the abstract-pictures subtest. Considered together, thesefindings are consistent with earlier studies of selective executive dysfunction in girls with Turner syndrome and suggest difficulty inhibiting strongly prepotent responses and a lack of organization in rapid retrieval of information but intact skills in planning ahead to execute a strategy and intact ability to shift response set.These findings parallel our recent study of working memory, using the Contingency Naming Test (CNT; Anderson, Anderson, Northarn, & Taylor, 2000; Taylur: Albo, Phebus, Sachs, & Bierl, 1987). Our study included 8- and 9-year-old girls with Turner syndrome (n =20) and girls in an age- and FSIQ-matched comparison group (n = 90). The CNT requires naming stimuli that vary in shape and color. Each stimulus includes a circle, square, or triangle that contains a smaller shape. Each outer shape is one of three colors. Naming of colors only, or outer shapes only, is all that is required during the two warm-up trials. During the two experimental test trials, participants name each stimulus on the basis of a one- or two-attribute contingency rule. The one-attribute rule requires naming the color if the inner and outer shapes match and naming the shape if the inner and outer shapes do not match.。

概要六顶思维帽方法六顶思维帽的目的是幸免思维混杂，按这种方式，考虑者在某一个时刻里就能够只按照一种模式考虑——而不是在某一时刻做全部的事。

对此最好的类比是彩色印图。

每一种颜色被印刷上去，最后它们就拼到了一起。

设计六种思维帽方法，是为了使我们从通常的争辩型思维向制图型思维转化。

这使得思维过程成了两个时期，第一个时期是绘制地图；第二时期是在地图上选择路线。

假如地图足够地好，那么最好的路线经常会变得特不明显。

和彩色印图相似，每一顶帽子在地图上表现为一种类型的考虑。

我并不认为六顶帽子差不多穷尽了思维的所有可能方面，然而它们的确涵盖了思维的要紧模型。

我也不认为在每一个思维瞬间我们都必须戴上某一顶帽子。

这些帽子极其强烈的人工特色是它们的最大价值所在。

它们为在需要一种确定类型的思维时提供了正式形式和方便性，不管是对某个自己依旧不的人而言，差不多上如此。

它们建立了思维这游戏的游戏规则。

任何参加这种游戏的人都要清晰地意识到这些规则。

这种帽子思维方式运用得越多，则它们就将越多地成为思维文化中的一部分。

在某一个组织中的每一个人都应该当学习这种差不多习语，以便使它成为其文化的一部分。

如此，就能够集中思维，使之更为强大有力，同时，它也通过一种活跃的和有约束性的方法代替了那种白费时刻的争论和漫无目标的讨论。

起初，我们或许会感到在使用不同帽子时，显得有点笨拙。

但这种笨拙感会专门快随着该系统的方便性日益显著而专门快消逝。

这些帽子的首次使用可能是在一次偶然的场合需要某顶帽子或者是在黑帽思路向其他思路转化的时候。

就象我在本书开始所写到的那样，这些帽子的一个巨大的价值就在于它们提供了思维角色。

一个考虑者能够为他能够扮演这种角色而感到骄傲。

假如没有这些思维的正式形式，一些考虑者就将永久地处于一种固定的模式中(通常是黑帽模式)。

我再强调一次，这是一个用起来特不容易的系统。

关于读者来讲，没有必要对我在书中所陈述的不同点进行死记硬背，这些东西差不多上详细的论述。
