摘　　要：采用Fortran语言自行开发的程序,在MPI编程环境下,对一新型燃烧器一次风喷咀及弯头组件内的气固两相流动进行了数值模拟。在求解过程中,将整个几何区域分解成若干相对简单的子区域,然后分别在各子域上对控制方程组进行离散多机并行求解。最后分析了计算机集群在数值求解复杂流动问题方面的实用性以及实际所能达到的计算效率。Using the program developed from Fortran language and under MPI environment, the gas-solid two-phase flow in the primary air nozzle and the elbow assemblies of a new burner was numerically simulated. In the solution process, the whole domain was divided into a number of simple sub-domains, the governing equations over each sub-domain were solved by discrete multi-parallel method. Finally, the practicability of computer cluster in numerical calculation of complex flow problems and the actual calculation efficiency were analyzed.
