Abstract(summary):

In this paper, the multi-material Eulerian method was used to study the fluid-solid coupling issues, such as the formation of shaped charge jet. An adaptive grid refinement algorithm, based on the Youngs' interface reconstruction algorithm, was proposed to treat the transportation of the mixed grids. In order to verify the efficiency of this algorithm in the actual physical field, the algorithm was added to the indigenously developed EXPLOSION-2D hydrocode. The copper liner shaped charge jet was numerically simulated. The simulation results were in good agreement with the experimental results. It demonstrated that the adaptive grid refinement algorithm was efficient.
