Abstract
The material point method (MPM) performs well in the field of computational solid mechanics with nonlinearity, large deformation as well as fracture and fragmentation. In order to improve the calculation ability and efficiency of the complex interface in the fluid-solid coupled problem, the MPM is extended to the numerical simulation of multiphase fluid dynamics. The MPM solution format for Euler equations with source terms is constructed in this paper, and the accuracy of which is verified by calculating a typical example with analytical solutions. Furthermore, this paper studies the complex gas-solid twophase flow dynamics process of the dust-gas shock tube by introducing two sets of material points, and analyzes the influence of different factors on the corresponding flow characteristics. The simulation results show that the dissipation effect is enhanced with the increase of particle mass concentration ratio, and the length of the relaxation also increases with the increase of particle diameter. It can be seen that it is feasible to apply the MPM to the calculation of multiphase fluid dynamics.
