External Flow – Comparing a CFD Simulation with Experimental Data


This video compares a CFD solution with experimental data. We will be creating a classic Coefficient of Pressure (Cp) plot. This process will include slice extraction, new frame creation, and XY line manipulation. Experimental data was gathered using pressure taps along the wing in a wind tunnel.

This third video in our External Flow Getting Started series, Comparing a CFD Simulation with Experimental Data, uses the ONERA M6 wing data set. You can find the link to the data in the description below. The ONERA M6 wing was tested by NASA in a wind tunnel at four different Mach numbers and various angles of attack. This is now a classic CFD validation case for external flows because it has a simple geometry, complex flows, and experimental data to validate against.

Thanks for watching!
