Ground effect on wing

hk.narahari · September 12, 2019, 08:14

It is known that as an aircraft approaches to land the proximity of ground alters it's CL, CD and CM behaviour. I was wondering if anyone in the forum has experience in simulating ground effect on a 2D airfoil. Looks like a decent project for an M.Tech student.
Any pointers would be of help to kick start the work

Robert Lee of OpenFOAM tutorials on youtube have done a video regarding this. You can find it here: https://www.youtube.com/watch?v=OfibQQFskcE

If you combine that video with this video: https://www.youtube.com/watch?v=LFn7ti4nCm8 presenting how to get the forces you could get the CL, CD and CM.

You could run the simulation at different heights from the ground.
