CPM, suggested by Nitsche, estimates the skin shear stress of transitional boundary layers by fitting the equation … WebSkin friction coefficient. The skin friction coefficient, , is defined by: Where is the local wall shear stress, is the fluid density and is the free-stream velocity (usually taken ouside of the boundary layer or at the inlet). For a turbulent boundary layer several approximation formulas for the local skin friction for a flat plate can be used:
