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.
