Abstract
There has been studied a lot of two dimensional hydrofoil sections for the boundary layers. This paper suggests that the plaiable roughness effects on boundary layer transition region of suction side for NACA 4412 hydrofoil sections provided by auxieiary shape factor and lag-entrainment effects. These results show that the laminar sepration. Transition and end of transition of the boundary layer due to pitting roughness effects, to the foil Reynold's number as well as to the angle of attack were delayed a little. And comparisons with valuable the other calculations and measurements show qualitative agreements.
