Hi all ,
im working on a simulation about car wings in ground effect. Im doing this in 2d first. Ive got the multi element airfoil and placed it 0.1 of the chord length away from ground. But when i run simulations i get a different result with Standard k-epsilon model and a different result with (k-w SSt and k-epsilon realizable) both k-epsilon models use Enhanced Wall treatment. What i get is higher Cl of 4 from former (which is expected) but a value of 2.7 much like in free stream from the latter models ?? Does this happen usually ? I cant decide how to fix this ? Please help out. |
