Abstract

This paper develops an MOCL algorithm for tracking moving interfaces in axisymmetric cylindrical coordinate. A finite difference Eulerian code with the algorithm is used to simulate the formation process of the shaped charge jet. The sensitivity of the tip velocity of the jet and its velocity gradient to the cone angle of the shaped charge liner is investigated numerically. The results reveal that the shaped charge jet with large cone angle has both the merits that explosively formed projectiles and the jet with small cone angle have. The numerical analysis also indicates that the developed MOCL algorithm has much better resolution for moving interfaces, especially effective for large deformation. The algorithm can also be applied to optimization design of shaped charge jet.
