摘要
针对交错网格下的SIMPLE数值算法实施了分区并行计算方法,在小型局域网下实现了流动和传热问题的并行数值计算。对两个经典的流动和传热问题的数值模拟实验表明,所建立的并行计算环境和分区并行算法能够得到正确的和收敛的数值结果。但与串行计算结果相比,并行计算误差明显大于串行计算误差。对并行算法做出的性能分析表明,所给出的并行算法得到了明显的加速效率。随着计算规模的增大,加速比和并行效率提高更显著。
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.
