The importance of turbulence near the wall

Dear all:
I wonder in what conditions that one can completly ignore the bondary layer in the wall by imposing free slip boundary condition. I am simulating a supersonic jet flow that flows near a wall, but all that I want to know is that the force generated by the jet impinging on an object mounted on that wall. How reliable is the simulation if I do not resolve the boundary layer near the wall (Just using high reynolds number k-e) knowing that my boundary layer must be very very small for supersonic flow (Mach=2.3). Thank's for any response and help Danny |
