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.
