A Method for the Calculation of the Turbulent Boundary Layer with Pressure Gradient

Abstract

A method of calculating the turbulent boundary layer is explained in this paper. The major assumption of this method is that the rate of increase of the boundary layer thickness is proportional to the turbulent velocity fluctuation due to the vorticity contained in the layer. The velocity profile which consists of two parts is assumed, then an equation is obtained. With this equation and the momentum integral equation, the boundary layer thickness and the velocity profile are determined.
