Three-Dimensional Separation and Vortical Wakes Over a Prolate Spheroid.

Abstract

A vortex lattice code was developed to generate potential flow solutions over three dimensional bodies. An approximate boundary layer technique is incorporated to allow the calculation of the line separation. The separated vortex sheets are modeled in terms of a vortex grid which is convected with the flow. Special conditions at separation determine the strength of nascent vorticity. Viscous inviscid interaction in three dimensions allows the accurate prediction of the line of separation and the pressure distribution over the attached flow region. Keywords: Three dimensional boundary layers; Three dimensional separation;: Three dimensional wakes; Skin friction lines.
