Abstract

A numerical algorithm for simulating gas dynamics in rotor–stator systems based on sliding meshes and edge-based schemes is described. The paper pays particular attention to the multilevel MPI + OpenMP parallelization for cluster systems. Parallel efficiency is demonstrated on up to 1400 cores as well as on Intel Xeon Phi accelerators. The scheme is verified by solving a linear acoustic problem. The robustness of the algorithm is demonstrated on the simulation of a model fan.

基于边缘方案的转子-定子系统流动仿真并行算法

摘要

描述了一种基于滑动网格和基于边的方案来模拟转子-定子系统中气体动力学的数值算法。本文特别关注集群系统的多级MPI + OpenMP并行化。在多达1400个内核以及Intel Xeon Phi加速器上展示了并行效率。通过解决线性声学问题验证了该方案。该算法的鲁棒性在模型风扇的仿真中得到了证明。
