Second order boundarylayer solutions for the stagnation flow of a circular cylinder
Abstract
In case of finite Reynolds number, secondorder solutions of the boundarylayer equation for the flow over a circular cylinder with separated wake are investigated in the vicinity of the stagnation point. The secondorder effects for wall shear stress due to the curvature of the cylinder and the displacement of main flow are discussed by introducing the method for higher order boundarylayer solutions developed by Van Dyke (1962). As a result, it is shown that the wall shear stress decreases proportionally to the Reynolds number raised to the minus onehalf power and that the effect of curvature amounts to 75 percent of the decreasing rate. Moreover, a new accurate method for solution of first order boundarylayer equation is proposed.
