摘要
Abstract
In this study we investigated the property of the shock wave propagating into the LiF window using the pole-curve method of two-dimensional unsteady flow theory and the hydrokinetical software LS-DYNA.The result derived from the pole-curve method shows that,when the one dimensional planar shock wave moves from the wedge-shaped explosive to the LiF window,the moving direction of the particles changes with the angle of about 3.3°,whereas the change angle actually obtained by the LS-DYNA simulation is 2.77°～3.03°.This disparity may be due to the fact that the rarefaction wave is ignored in the pole-curve method.关键词
