Method for the Approximate Calculation of the Skin Friction Coefficient of Horizontal Wavy Plates

摘要

A method for a simple and approximate calculation of the wall shear stress distribution in a steady, two dimensional, laminar and incompressible boundary layer flow along a horizontal plate was developed. It is shown that for zero amplitude of oscillation the solution obtained by the approximation method is in very good agreement with Blasius' exact solution for flat plates. The method is useful for perturbations of 1 to 5 percent. For inviscid flow field calculation where only the prediction of the point of separation is required, calculation time is less than that of integral methods.
