Abstract

Abstract : A method is described for the calculation of the development of incompressible turbulent boundary layers in pressure gradients, so that drag and separation of flow may be predicted more accurately. The principal contribution is the form ulation of new relations for the variation with pressure gradient of (1) the shearing stress at the wall (local skin friction) and of (2) the integral of the shearing stresses across the boundary layer for use in a moment-of-momentum equation recently derived by Tetervin and Lin. With the assumption of the one-parameter characterization of velocity profiles by a shape parameter H, the moment-of-momentum equation and the von Karman momentum equation constitute a working method involving the solution of a pair of simultaneous first-order differentail equations.
