本文采用NND格式求解Euler方程组,模拟深层水域强爆炸以及冲击波固壁反射后的流场。
The blast in deep water and its reflection at solid wall are computed by means of the NND scheme for the solution of Eulerequations.The calculated results of the spherical blast in deep water arein good agreement with those measurements in WIGWAM test,the nu-merical results of the irregular reflection of blast shock wave from rigidwall in air are comparable to previous theoretical results ̄[5].A consid-erable amount of the characteristics obtained from the computation of thereflection of blast shock wave under deep water indicates that there is anapparent difference in the flow properties between blasts in air and underdeep water.Therefore,an appropriate state equation of water is importantfor numerical prediction of the underwater blast phenomena.
