课程简介

课程名称:Ansys Fluent 第7章 课程概述: 本课程主要分为三个章节,重点介绍Ansys Fluent中的建模、网格划分和热传递的相关知识。 第一章:Ansys Space Claim(Fluent建模) 在这一章中,学员将学习如何对现有模型进行简化,以便为网格划分做准备。课程还涵盖了体积提取和封闭结构的创建,以及如何处理装配部分,学习创建共享拓扑和合并面的技巧。 第二章:Ansys Meshing(局部网格控制) 本章的内容专注于局部控制网格方法,学员将掌握多种网格生成方法,包括自动、四面体、六面体主导、平扫等。同时,学员还将学习不同的网格尺寸控制选项,包括边、面、元素大小,以及影响区域和全局大小因子等技巧。此外,将介绍通胀、卷缩、面网格划分和节点移动等高级网格控制方法。 第三章:Ansys Fluent(热传递) 在最后一章中,学员将学习热传递的类型,包括对流、传导和辐射。课程内容还涉及到墙体的热传递建模、墙体网格划分、指定墙体厚度及壳体传导等选项。学员将进行后处理分析,并了解加热空气的自然对流及热辐射建模。课程还包含多个实践环节,涵盖通过管道的热传递演示和对流热传递的综合案例。 总之,这门课程通过理论和实践相结合的方式,帮助学员深入理解Ansys Fluent在流体力学模拟中的应用,特别是在热传递方面的建模和分析技能。
