Leeside Flow Field Description over Cones at Large Incidence

Abstract

A semi-empirical analytic model for leeside flow field behavior over sharp circular cones at large incidence is described. The methodology involves replacement of the actual body by an inviscid equivalent body over which the flow field is developed. The equivalent body is selected by a combination of turbulent boundary layer analysis up to the primary separation point and correlation of available experimental results within the separated regions. The inviscid flow field over the equivalent body is developed by means of a numerical finite difference marching technique (Kutler program). Computer programs for implementing the analysis were developed and delivered to the AFFDL/FXG together with user's manuals. The performance of these programs is demonstrated by several numerical examples and comparisons with experiment.
