Abstract

This article introduces a numerical scheme to simulate aero acoustics propagation. The wave equation is discrete spatially with collocated finite volume method and Eulerian implicit method in time domain. The performance of the PC is greatly developed, so as expected the network can provide great computational capability. Based on this point, we developed a data structure system and parallel code. Two simple test cases have been done with the program and reasonable results were obtained.
