Fourth-Order Keller Box Solution of the Incompressible Axisymmetric Boundary Layer Equations.

Abstract

A computer code has been written for a general finite difference solution procedure of the incompressible boundary layer equations on a body of revolution. The procedure, a fourth-order accurate extension of Keller's Box Method, is capable of treating laminar or turbulent boundary layers up to a separation point and includes transverse curvature effects. The analysis has been coded for the Penn State IBM 370/3033 computer and has been shown to provide solutions comparable in accuracy to similar second-order schemes but with fewer grid points and with less computer time. Results and comparisons with both experiment and second-order methods are presented in graphical form for a low-drag body of revolution. (Author)
