can slip boundary condition in openFoam mean "inviscid wall" ?
 

Hi
I am simulating the flow over an multi element airfoil, i have studied in a research that for simulating the correct experiment conditions "we should reat the wind-tunnel walls as inviscid walls"
now my question is that, how can i define the "inviscid wall" in openFoam?
if we set slip boundary condition for the top and bottom side of our domain,can this boundary condition in openFoam mean "inviscid walls" ?

i mesh a squre domain around my sirfol, i put the freestream for the inlet and outlet patch (left and right side), i don't know what boundary condition should i use for topAndBottom side!

please guide me:o
Thank you very much

hi dear S.m.....as i know about boundary condition in openfoam for an airfoil you could use slip condition for top and bottom of your domain.GOOD LUCK
here is a training for how to simulate flow around an airfoil in open foam

Thank you, but my question is that, how can we chose inviscid wall for topAndBottom ?
