Algorithm study on interface tracking in Eulerian code

By means of comparison and summary of material interface disposal methods in Eulerian code, a new method dealing with multi-material interface is put forward in this paper. For the purpose of verifying the feasibility of this method, numerical simulation is done concerning the process of formation and penetration of the shaped charge jet of oil perforating bullet. The computation results are consistent with actual physical image. It thus proves that this method can more exactly simulate the phenomenon of relying on geometry shape of interface. To improve the resolution of material interface and field variable and make it closer to actual physical image of the material, local adaptive mesh refinement scheme is proposed.
