| Abstract: | Base on the Delaunay triangulation criterion in conjunction iwth the automatic point creation and the local grid regeneration method, unsteady flows induced by an accelerating projectile are investigated numerically by using the finite volume method. The unsteady effect on the wave structure in the flow field is examined thoroughly. |
