Parallel computation of fluid flow and heat transfer by subarea technology

A subarea parallel computation method is proposed and analyzed for fluid flow and heat transfer on a Local Area Network (LAN) for the SIMPLE algorithm with staggered-grid. The calculating of two classical fluid flow and convection heat transfer problems showed that the subarea parallel computation method on LAN environment have good convergence and accurate numerical results. Comparing with the serial computation method, the parallel computation method caused greater numerical error. The performance analysis of parallel algorithm indicated that it has obvious speedup. With increasing of grid size, the speedup and the parallel efficiency both elevated conspicuously.
