Sahu, J; Steger, J L

The three-dimensional flows over a projectile were computed using an implicit, approximately factored, partially flux-split algorithm. A simple composite grid scheme was developed in which a single grid is partitioned into a series of smaller grids for application that 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 was 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/sup 0/ angle of attack was computed using a fine grid and compared with experiment.
