Generation of the Starting Plane Flowfield for Supersonic Flow over a Spherically Capped Body
Abstract
This report describes a fast method to provide a three dimensional starting flowfield to be used in a space-marching-type calculation for the afterbody flowfield of spherically capped missiles at incidence in supersonic flight speed. Utilizing the property of spherical symmetry of the flowfield about a sphere, three dimensional starting plane flowfield may be interpolated from the results of an axisymmetric flowfield about a sphere, which is available from an existing computer program (NOSTIP) with considerably less computing time. The analysis of the interpolation method, examples and listings of computer programs for the axisymmetric and the three dimensional starting plane flowfields about a sphere in the Mach number range from 1.5 to 10 and angle of attack between 0 to 35 degrees are presented.
