Abstract

This paper discusses some experiences of the authors with the application of an explicit cell centered finite volume upwind TVD(MUSCL) formulation of the Roe's Approximate Riemann Solver for the computation of 3D inviscid and viscous high speed flows past blunt body configurations of practical interest.Local time stepping and parallelization techniques are employed to accelerate convergence in terms of effective wall clock times. The parallel machine used is the Flosover, which is based on the Intel i860 chip. A four-node version of the machine has been employed in the present work. A streamwise domain decomposition technique is employed for the parallelization.The study involved axisymmetric bodies for which a full 3D grid (360) is generated and no symmetry boundary conditions are imposed.
