CFD Training Course by ANSYS Fluent Software for Beginners, 5 Sessions

CFD Training Course

This CFD Training course by ANSYS Fluent helps you find your CFD way.

WHAT IS CFD?

Computational Fluid Dynamics (CFD) is the analysis of fluid flows using numerical solution methods. Using CFD, you are able to analyze complex problems involving fluid-fluid, fluid-solid, or fluid-gas interaction. Engineering fields where CFD analyses are frequently used are, for example, aerodynamics and hydrodynamics, where quantities such as lift and drag or field properties such as pressures and velocities are obtained. Fluid dynamics is involved with physical laws in the form of partial differential equations. Sophisticated CFD solvers transform these laws into algebraical equations and are able to solve these equations numerically and efficiently.

WHY DO WE NEED CFD?

CFD analyses have a great potential to save time in the design process and are, therefore, cheaper and faster compared to conventional testing for data acquisition. Furthermore, in real-life tests, a limited number of quantities is measured at a time, while in a CFD analysis, all desired quantities can be measured at once and with a high resolution in space and time.

HOW DO I START LEARNING HOW TO WORK WITH CFD TOOLS??

By using the tutorial videos prepared by the skilled CFD engineers in the MR-CFD group, even a normal person with a very small knowledge of CFD and Mechanics would be able to apply and exploit this powerful tool, whether for a professional task or just for simple academic or non-academic projects.

In the following tutorials, we will build different projects from scratch, meaning that you will learn how to build your desired geometry, how to generate structured or unstructured mesh for it, and finally, how to set up the FLUENT software to acquire the best results.

WHAT WILL I LEARN DURING EACH SESSION??

                1^st session:

In this session, we will mainly talk about the theories behind fluid problems and different approaches to solving them. Then we will solve a 2D Poiseuille flow theoretically and using the Navier-Stokes equations. Afterward, the same problem is simulated inside Fluent software and the acquired results are compared with the theoretical correlations. (ANSYS Fluent)

                2^nd session:

In the 2^nd session, we will solve the same previous problem in the 1^st session. However, the difference is that this time we will take heat transfer into account and also use the axisymmetric assumption meaning that we will solve a 3D problem but in 2D domain using the cylindrical coordinates. Finally, we will extract different results, such as the Nusselt number value and so on. (ANSYS Fluent)

                3^rd session:

In this video, we will explain how to import a NACA 0015 airfoil into the design modeler software, how to perform structured mesh over it, how to define Fluent software settings, and finally, last but not least, how to extract diagrams and values for forces like DRAG, LIFT and their coefficient. (ANSYS Fluent)

                4^th session:

In this tutorial video, we will simulate the fluid flow inside a pipe and perform structured mesh for it. We will enable the energy equation in our model to simulate the realistic heat transfer between the fluid passing inside the pipe and our pipe wall. Finally, we will extract the average Nusselt number for the whole surface’s pipe and also teach you how to obtain the local Nusselt number in any cross-section you’d desire. (ANSYS Fluent)

                5^th session:

Now in this session, we will teach you how to simulate compressible flows over an airfoil or any other object you have in mind. We will build a 3D model of the NACA 0012 airfoil and put it inside a domain where the flow enters with a Mach number equal to 0.7. Also, we will define an angle of attack for our airfoil and calculate the parameters like a drag, lift forces, and their coefficients, and compare them with the simulation results published by NASA.
