| Abstract: | Based on 3D unstructured grid,the high precision TVD format was applied to the study of numerical simulation for phenomena of armor piercing fin-stabilized discarding sabot(APFSDS) projectile separating and discarding flow.A parallel arithmetic on the basis of message passing interface(MPI) parallel environment on PC-Cluster system for the shock wave flow field was discussed.The results indicate that the parallel computation is practical and efficient for simulating complicated flow field. |
