摘要 本文通过求解任意坐标系下的定常雷诺平均N-S方程和SST两方程湍流模型,采用五阶精度的加权紧致非线性格式(WCNS-E-5),实现流场的高精度数值模拟;基于分布式存储系统,采用MPI并行编程环境、非堵塞通信机制和遗传算法负载平衡,实现高精度模拟软件的并行化。在国防科学技术大学高性能计算应用研究中心的"天河"系统上完成软件移植、测试,通过对DLR-F6翼身组合体的模拟,说明软件并行策略和开发的正确性。最后,实现某民机全机的高精度并行模拟,网格规模达到1亿,为下一步WCNS高精度并行软件的大规模工程实际应用打下了坚实基础。 Profiting from the fifth-order accurate explicit WCNS0 high-order numerical simulations software is developed by solving the Reynolds-Averaged Navier-Stokes equations together with the SST two-equation turbulence model in eurvilinear coordinates. Based on the distributed storage system, a parallel version is accomplished adopting the MPI parallel programming environment, non-blocking algorithm and greedy-algorithm- based load balance strategy. Software is moved to and tested at the Galaxy stars system of the High Performance Computing Application Research Center of NUDT. Simulation of DLR-F6 shows that the parallel strategy is proper and the development is valid. Finally, high-order parallel simulation of some full civil aircraft is implemented, whose gird points number is 105 million. This work will lay a solid foundation for the future massive engineering application of WCNS high-order parallel software.
