Introduction to Aero-Thermal simulation using Ansys Fluent : Skill-Lync

Computational Fluid Dynamics has made it possible to study fluids and understand their behavior in different environments. CFD tools are now easily accessible from the comfort of your living room thanks to computers. These tools have had a significant impact on the development of many industry applications. CFD can be used to simulate anything from a simple flow through a pipe to complex flows inside combustion chambers. Both cases can be solved using the same equations, called the Navier Stokes equations. However, complex simulations require additional equations. This course will help you understand what to apply and where to apply it.
A CFD simulation includes three components. The pre-processing, the solver, and the post processor are the three parts of a CFD simulation.
Pre-processing is the part that prepares your geometry for analysis. No matter what geometry you throw at the computer, it cannot solve it. It must first be Discretized. What is discretization? It is the conversion of your physical domain to your computational domain. While the Navier Stokes equations can be described as a collection of partial differential equations, they cannot be solved by computers. This is what happens in the discretization process. This helps the computer to identify the areas where it must solve the equations. It is based on the material characteristics that we assign the domain.
The solver section deals with using the N-S equations in order to obtain the required results. It is essential to use the correct boundary conditions and Turbulence model to simulate flow. If you don't tell the computer what you want, it will not know what you need. It is therefore important to set up the solver.
You need to verify the simulation results after you have solved it. This is the post processing. Although you can see a lot of colorful plots on the screen, it is important to fully understand what you are looking at. This is where the post processor can help.
This course will teach you how to use ANSYS, a commercial program.
ANSYS can be used to simulate multiple physical systems. We will use the following tools to help us understand the three components of this process.
The pre-processing portion
CFD ICEM
ICEM CFD has many options to create the right mesh for your geometry. It can create both a structured as well as an unstructured mesh. You can also use the various mesh diagnostic tools it has to assess the quality of the created mesh.
ANSYS Mesher
ANSYS Mesher, another pre-processing tool within the ANSYS package, is also available. This tool has the same capabilities as ICEM, but it offers less control over the mesh.
For the solver
ANSYS FLUENT
ANSYS FLUEN is a leading industry flow simulation software that can simulate many types of flows.
For the post processor
ANSYS FLUENT
ANSYS FLUENT comes with an integrated post processor that can provide all the results you need.
This course will take you through the basics.
