It covers the basic workflow, setup, and analysis of a typical fluid flow problem.2.1 Creating a StudyThe first step in using SolidWorks Flow Simulation is to create a new study. This involves defining the fluid domain, selecting the appropriate fluid type, and specifying the boundary conditions.2.2 Meshing the GeometryAfter creating a study, the next step is to generate a mesh for the geometry. Meshing is the process of dividing the fluid domain into a network of small cells or elements. A finer mesh provides higher accuracy but requires more computational resources.2.3 Defining Boundary ConditionsBoundary conditions define the inputs and outputs of the fluid flow problem. This includes specifying the inlet velocity or pressure, outlet conditions, wall properties, and any additional constraints or assumptions.2.4 Solving the Flow ProblemOnce the geometry is meshed and the boundary conditions are set, SolidWorks Flow Simulation can solve the flow problem.

These features allow engineers to handle more complex fluid flow problems and obtain more detailed insights.3.1 Turbulence ModelingTurbulence modeling is crucial in accurately simulating turbulent flow, which is common in many real-world scenarios. SolidWorks Flow Simulation provides various turbulence models, such as the k-epsilon model and Reynolds stress model, to capture turbulence effects.3.2 Multiphase FlowMultiphase flow refers to the simultaneous flow of multiple fluid phases, such as gas-liquid, liquid-solid, or gas-liquid-solid. SolidWorksFlow Simulation offers tools to model and analyze multiphase flow phenomena, such as cavitation, droplet dynamics, and particle transport.3.3 Heat Transfer AnalysisSolidWorks Flow Simulation includes comprehensive heat transfer analysis capabilities. Engineers can analyze conduction, convection, and radiation heat transfer within their designs. This is particularly useful in evaluating thermal management solutions and optimizing heat dissipation.3.4 Fluid-Structure Interaction (FSI)Fluid-structure interaction occurs when the fluid flow affects the structural behavior of a design, and vice versa. SolidWorks Flow Simulation allows engineers to perform FSI analysis, enabling them to study the interaction between fluid forces and structural responses.Chapter 4: Case Studies and Real-Life ExamplesChapter 4 presents several case studies and real-life examples that demonstrate the practical applications of SolidWorks Flow Simulation.

基于Solidworks和Fluent的管壳式换热器换热管腐蚀现象广泛存在于化工机械中。
本文通过硬度测试试验分析管壳式换热器腐蚀与换热管硬度间的关系,证明引起换热管腐蚀的主要原因不是流体介质腐蚀,而是自身结构设计的不合理。
为了对换热管进行结构优化设计,运用流体软件CosmosFloworks和Fluent对换热器进行建模与仿真,研究换热器自身结构对腐蚀现象的影响。
最后,在试验与仿真的基础上提出了换热器结构优化方案。
换热器是化工、石油、动力、冶金、船舶、交通、食品和机械等工业部门广泛使用的一种通用设备,换热器对整个企业的投资和发展有着重要影响,据统计在化工生产设备中,换热器约占总投资的30%~40%。
换热器换热状况的好坏直接影响到整个装置的平稳运行及综合经济指标,并且对生产的安全、稳定和长期运行起着重要作用。
长期以来,管壳式换热器以其结构坚固、可靠性高、适应性强和选材广等优点在换热器的生产和使用数量上一直占主导地位。
由于其结构的复杂性和使用工况的多样性,常常出现换热器的局部失效甚至整体报废,进而影响到了换热器的工作效率和正常的工艺性能。
管壳式换热器使用一段时间后会发生泄漏失效,漏点通常出现在列管与管板连接处,并且伴有腐蚀现象。
通过焊接的方法对换热器漏点进行堵塞只能暂时性解决问题,过一段时间后又会出现腐蚀失效现象,因而找出换热器失效机理已经成为迫切的课题之一。
本文首先通过硬度测试试验分析管壳式换热器腐蚀与换热管硬度间的关系。
然后运用Solidworks和Fluent软件对换热管腐蚀与换热管内壁的粗糙度,换热管的流速和换热器自身结构之间的关系进行研究,并在此基础上提出了结构优化方案。
本文不是单纯的从流体介质的腐蚀性、电化学反应、应力腐蚀、缝隙腐蚀或一系列事后补救措施来解决换热器的腐蚀问题,而是从根本上提出了预防换热管腐蚀的方法。
本文中运用了计算流体动力学CFD(Computational Fluid Dynamics),对流态进行数值仿真模拟计算。
