Abstract

AbstractIn this paper, we investigate the parallel solution of rotating internal flow problems, using the Navier–Stokes equations as proposed by Speziale and Thangam (in 1983) and Speziale (in 1985). A Runge–Kutta time‐stepping scheme was applied to the equations and both sequential and message‐passing implementations were developed, the latter using MPI, and were tested on a four‐processor SGI Origin200 distributed, global shared memory parallel computer and on a 32‐processor IBM 9076 SP/2 distributed memory parallel computer. The results show that our approach to parallelize the sequential implementation requires little effort whilst providing good results even for medium‐sized problems.
