For many quite arbitrary geometries, the programming constraints imposed by vector processors (parallel or pipeline) are less restrictive for three-dimensional computations than for two-dimensional ones. This is demonstrated by presenting three-dimensional solutions that were computed on the Illiac IV, by showing how they were formulated on that computer, and by discussing how similar formulations could be arried out on other array processors. Both implicit and explicit numerical procedures are used; all results presented are for high Reynolds numbers and are based on the compressible, Reynolds averaged, Navier-Stokes equations with thin-layer turbulence modeling. The results themselves are new and of practical importance, although resolution of three-dimensional flow fields is still constrained by available computer capacities. (DePo)
