Numerical Simulation of Three Dimensional Transonic Flows.

Abstract

The three dimensional flows over a projectile have been computed using an implicit, approximately factored, partially flux-split algorithm. A simple composite grid scheme has been developed in which a single grid is partitioned into a series of smaller grids for application which require an external large memory device such as the SSD of the CRAY X-MP/48 or multi-tasking. The accuracy and stability of the composite grid scheme has been tested by numerically simulating the flow over an ellipsoid at angle of attack and comparing the solution with a single grid solution. The flow field over a projectile at M = 0.96, 1.1. and 4 deg angle of attack has been computed using a fine grid and compared with experiment. Keywords: Asymmetric shocks; Navier Stokes equations.
