课程名称：掌握ANSYS Fluent中的CFD分析 课程概述：在工程分析中，CAD模型起着重要作用。然而，这些模型可能存在诸如面合并、曲线重复、多余边缘、边缘分裂、间隙或干涉等错误。因此，我们需要避免有缺陷的CAD几何结构，以确保能进行无错误的几何修复与转换。为了避免建模错误，选择正确的物理模型至关重要。在流体动力学中，最重要的模型是一组称为Navier-Stokes方程的偏微分方程。 在修复完毕并获得正确的几何结构后，我们需要进行离散化或网格划分。为了获得准确的结果，必须专注于提高网格质量，因为网格越好，解决方案也越好。为尽量减小离散误差，我们需要不断进行网格划分和重新划分，直到达到最小误差。实现准确解后，我们可以称之为满足收敛标准。 在有限元分析（FEA）、计算流体动力学（CFD）或任何工程分析中，网格划分或离散化都发挥着至关重要的作用。有时，几何体或CAD模型中可能存在交叠的固体或表面，会出现各种错误。因此，这种情况下我们无法进行完美的网格划分。因此，我们需要使用ANSYS的空间修复工具纠正这些错误。 在本课程中，我们将介绍不同的网格方法如密闭几何体和容错网格，这些都是ANSYS 2021版本中新引入的技术。课程按不同的工程应用和技术需求进行了分类，共分为三个单元，共20个与工业应用相关的视频。 单元一：ANSYS Fluent容错网格的CFD流分析（10个视频） 单元二：ANSYS Fluent密闭几何体的CFD流分析（4个视频） 单元三：传统ANSYS Fluent流的CFD流分析（4个视频） 通过这门课程，学员将掌握使用ANSYS Fluent进行CFD分析的高级技术，并能在实际工程应用中灵活运用。
In engineering analysis, the CAD model plays an important role. It may have errors like merged faces, duplicate curves, extra edges, split edges, gaps, or even interference errors. Therefore, we need to avoid dirty CAD geometry, which needs to be repaired and converted to error free geometry. To avoid modeling errors, it is important to select the correct physical models. The most important model for fluid dynamics is a set of partial differential equations called the Navier-Stokes equations.After getting error-free, correct geometry, we need to go for discretization or meshing. To have an accurate result, we need to focus on better meshing quality because the better the mesh, the better the solution. To minimize the discretization error, we need to go on meshing and remeshing again and again till we reach the minimum error. When we get the exact solution, we say that the convergence criteria have been met.From this theoretical understanding, we can realize that in FEA, CFD, or any kind of Engineering analysis, meshing or discretization play a very important role. Sometimes the geometry or the CAD model may have some intersecting solids or surfaces. It may have errors like merged faces, duplicate curves, extra edges, split edges, gaps, or even interference errors. In these cases, we cannot go for perfect meshing. Therefore, we need to rectify those errors using the ANSYS space-claim repair tool, and even then, we can share topology. So, if we require perfect meshing, and after that, if we want to go for different types of analysis like structural or CFD analysis, we must say that ANSYS is the best software. Here, to have perfect meshing, we can adopt different meshing methods like watertight geometry and fault tolerant meshing, which are new to the ANSYS interface and have been introduced in the ANSYS 2021 version. Therefore, to be familiar with these new techniques, we have developed this course considering different types of engineering applications with advanced techniques like watertight geometry, fault-tolerant meshing as well as conventional approaches.Accordingly, we have categorized this CFD course into three different units consisting of twenty videos relevant to industrial applications.The first unit comprises ANSYS Fluent Fault-Tolerant Meshing, consisting of ten videos.The second unit comprises ANSYS Fluent watertight geometry, consisting of four videos, and the third unit contains four videos with the conventional approach of CFD Fluent flow analysis.Unit 1: CFD Flow Analysis with ANSYS Fluent Fault Tolerant Meshing:(i) Introduction to the Course(ii) CFD Heat Transfer Analysis through a Shell-Tube Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(iii) CFD Heat Transfer Analysis through a Counter-Flow Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(iv) CFD Heat Transfer Analysis through a Cross-Flow Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(v) CFD Heat Transfer Analysis through a Condenser Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(vi) CFD Heat Transfer Analysis through a Plate Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(vii) CFD Heat Transfer Analysis through a Surface Condenser using ANSYS Fluent Fault Tolerant Meshing(viii) CFD Fluid Mixing through a Special type Heat Exchanger using ANSYS Fluent Fault Tolerant Meshing(ix) CFD Heat Transfer Analysis through an Exhaust Manifold using ANSYS Fluent Fault Tolerant Meshing(x) CFD Heat Transfer Analysis through Catalytic Converter using ANSYS Fluent Fault Tolerant Meshing(xi) CFD Heat Transfer Analysis through a Wind Tunnel using ANSYS Fluent Fault Tolerant Meshing(xii) CFD Heat Transfer Analysis through a Venturi-meter using ANSYS Fluent Fault Tolerant Meshing(xiii) CFD Heat Transfer Analysis through an Expander using ANSYS Fluent Fault Tolerant Meshing(xiv) CFD Heat Transfer Analysis through Heat Pipe using ANSYS Fluent Fault Tolerant Meshing(xv) CFD Conjugate Heat Transfer Analysis using ANSYS Fluent Fault Tolerant MeshingUnit 2: CFD Flow Analysis with ANSYS Fluent Watertight Geometry:(i) CFD Watertight Geometry Workflow through a Wind Tunnel(ii) CFD Heterogeneous Fluid Mixing using ANSYS Fluent Watertight GeometryUnit 3: CFD Flow Analysis with conventional ANSYS Fluent Flow(i) CFD Flow Analysis Over a Cylinder Surface using ANSYS Fluent(ii) CFD Intermixing of Fluids in a Bent-Pipe using ANSYS Fluent(iii) CFD Flow through a Converging & Diverging Section (2D) using ANSY Fluent(iv) CFD Flow through a Venturi-meter using ANSYS Fluent
