摘要：

In order to solve the problem of three-dimensional two medium transportation problems of fluid dynamics, the transportation principles of a metal ball moving in constant velocity fields were given. The space district was dispersed into some cuboid Euler cells in the directions of three coordinate axes, along which mediums were transported by turns. The continuous boundary condition was adopted to simulate infinite boundary. The interface reconstruction method in the mixture cells was the volume fractions method. The numerical simulation result indicates that the shape and size of the medium cuboid can keep unchanged basically during the medium transportation. The overspeed transportation problem of the volume fractions method in the course of transportation is pointed out. The research may provide certain reference and guidance for solving the multi-material fluid dynamics problems.
