An Axisymmetric, Strong-Interaction Procedure to Include Large, Normal Pressure Gradients.

Abstract

This report presents a modified strong-interaction procedure for axisymmetric bodies. The modifications include the addition of the normal momentum equation to the boundary-layer calculations and the patching of the viscous-inviscid flow solutions at the boundary-layer edge to account for large, normal pressure gradients. The resulting weakly elliptic problem is solved by an iterative technique. Based on results to date, the use of an under-relaxation factor and some smoothing are required to obtain a converged solution. (Author)
