Abstract
A parallel algorithm for direct solution of the three-dimensional Navi er-Stokes equations using a spectral scheme has been developed and suc cessfully implemented on a 3-processor multicomputer. The algorithm ut ilizes the parallelism inherent in the spectral representation of the Navier-Stokes equations. Communication between the processors has been kept at a minimum, and most of the CPU time is dedicated to computati on. The actual solutions on 323 and 643 grids have resulted in paralle l efficiency of between 87.2% and 97.3%.
