Abstract
En 中文
In the development of numerical schemes for compressible multifluids, the treatment of the interface is very important. In this paper, we proposed a numerical method based on interface interactions where the ghost cells of the ghost fluid method, GEM [J. Comput. Phys. 152 (1999) 457], are determined by solving the real interface interaction and the hypothetical ghost interaction. Extensive tests in ID are carried our, and with the 2D examples suggest that the present scheme is able to handle multifluids problems with large difference of states and material properties at interface while still keeping to the simplicity of the original GFM.
