Ground Effect Vehicle Airfoil Simulation in OpenFOAM

All code can be found at: github.com/lor...
DESCRIPTION:
Here we will be doing a simple 2D simulation of a ground effect vehicle airfoil. This is simply an airfoil that is some small multiple of its chord above the ground.
OUTLINE:
-Go over mesh.
-Go over boundary conditions.
-Run simulation.
-View results.
COMMANDS:
gmsh mesh/main.geo -3 -o test.msh
gmshToFoam test.msh -case case
Modify boundary file.
pimpleFoam

"...These kinds of vehicles aren't seen that often these days..."
Conventional airplanes regularly transition into and out of ground effect every time they take off and land. A pilot that does not account for this does so at his own peril.

I want to build a ground effect prototype vehicle ... Radio controlled ... how do you go about deciding what type of airfoil shape to use? Why BSpline?... is there one or a type of airfoil that would work best as opposed to flight at altitudes above one wingspan?

Do you have any Tutorial haw man can make Mesh around Profile?

[@Syh0420]

Hi, I have tried to use the exact same setting as you, but I couldnt run the simulation. I am not sure where I do wrong.

[@JordanHinsonLikeTheRiver]

How far into the video do you see the wing without the ground for comparison?

[@user-fl6fv3yv5q]

How about the BC setup? Can I know the details?

[@mzulfadh]

Thanks for your explanation,
but, when i run first command : gmsh mesh/main.geo -3 -o test.msh
it comes : -bash: gmsh: command not found
can you help me?

Hi, I am trying to use snappyHexMesh to mesh around an aerofoil, but upon trying to run sHM, I get this error:
Shell aerofoil.obj does not support testing for inside - but i created the aerofoil in freeCAD and it definitely is closed!

does OpenFOAM handle supersonic flows?
I'm curious about ground effect at such velocities.

[@diegojolin]

I just wonder why there is no boundary layer in the solution?

[@OpenFOAMTutorials]

+Diego Garcia Pardo Do you mean a fine boundary mesh? This is indeed a coarse simulation. You can refine it to your needs.

[@diegojolin]

+OpenFOAM Tutorials my bad, I just look at the video again. I thought I was looking at the velocity fields when it is the pressure field what you presented. Sorry for that

[@UFOMAN618]

nice job, wondering how you set this up, i would liek to get paraview workign this simply with no console commands...

[@DaylightDigital]

Where did you get your mesh from?

[@lordvon64]

+DaylightDigital Hi, I made it in Gmsh. The shape I got from an airfoil data website.

[@DaylightDigital]

+lordvon64 Do you think it would be difficult to mesh an airfoil with a Gurney Flap in Gmsh?

[@OpenFOAMTutorials]

+DaylightDigital No problem. See my tutorial on baffles. ruclips.net/video/7Ex1RHDQqIc/видео.html
