摘要
Abstract
Parallel computing is a development trend of the CFD technology. In this paper, by considering the character-istics of hypersonic flow, we make a study of the CFD parallel computing method based on structural multi-partition grids. To preserve the continuity of the flow field, we focus on solving the problem of data exchange between the different zones and the treatment of boundary conditions. A finite volume method is introduced, and the total variation diminishing scheme proposed by Osher and Chakravarthy is adopted for spatial discretization. In this paper, MPI is used for data exchange, and then a series of tests are done on the PC cluster. The results show that the method is feasible and accurate.关键词
