Numerical Solution of Complete Flows Around External Stores.

Abstract

A computer code, based on a finite element algorithm, was developed to solve the governing equations for a three-dimensional flow around a spherically blunted cone at an angle of attack. The solution is valid for a boundary layer region, including the flow separation in the cross-flow direction in the leeward area. The required initial and boundary conditions for this solution are obtained from a finite difference computer program for laminar compressible three-dimensional boundary layer flow. Extension of the analysis to include the turbulent transport using the mixing length theory and a two-equation turbulence model is described. The results demonstrate the capability of the finite element method to predict the three-dimensional boundary region flow with cross-flow separation in the leeward area and to model the effects of turbulent flow.
