## Description

In this project, a wind tunnel and a specific body that is placed inside it, are modeled by ANSYS Fluent software.

This project aims to investigate the drag force on this body. Geometry is designed in ANSYS design modeler® and is meshed in ANSYS meshing®. The mesh type is unstructured and the total element number is 179542.

The wind tunnel is one of the most widely used aerodynamic testing devices today. Among the many experiments that can be performed in wind tunnels, we can mention the testing of various structures, including various types of airfoils, planes, static structures, etc.

The purpose of these experiments is usually to investigate the aerodynamic conditions and visibility of the flow lines.

The free fall test can also be performed in a tunnel to examine the effects of airflow on a falling object. Due to the importance of the effects of the forces, including drag, on the body, the calculation of these forces is important, which can be calculated with the help of CFD.

## Wind Tunnel Methodology

The energy model due to the compressible flow solver (density-based) is activated in this simulation.

## Wind Tunnel Conclusion

We have obtained the contours of velocity, pressure, temperature, etc. for different inlet Mach numbers at the end of the solution. The velocity vectors show the formation of separation vortices behind the tunnel.

Also, due to the separation, the flow turbulence behind the tunnel is considerable and greater than in other parts of the computational range.

6. Dr. Candido Raynor MD

I was fascinated by the results! It’s incredible how the simulation manages to illustrate the formation of separation vortices clearly. Could you expand on how accurately the CFD model predicts the size and location of these vortices compared to real-world physical wind tunnel tests?

• MR CFD Support

Thank you for your kind words! The CFD simulations using ANSYS Fluent are quite advanced and capable of predicting flow phenomena like separation vortices with high precision. However, the accuracy largely depends on the quality of the mesh, the suitability of the turbulence model employed, and how well the physical boundary conditions are defined. In ideal scenarios, the CFD model aligns closely with wind tunnel experiments, still occasional validation with physical tests is recommended for critical applications to ensure reliability.
