摘　　要：火炮膛内气固两相流动存在各种各样的复杂边界,对这些边界的计算处理是数值模拟膛内现象成功的关键之一。本文结合作者的数值实践,就内弹道一维两相流动给出了固壁边界和底火射流边界处理的一种新方法,并用这种方法对30mm火炮膛内压力波进行了成功的数值模拟。A variety of complicated boundaries exist in the gas-solid two-phase flow in guns. Treatment of these boundary conditions is a key to the successful simulation of two-phase phenomena in guns. In the light of the author's practice, this paper presents some new methods in the treatment of the solid wall boundary and primer jet boundary, with the help of which the pressure wave in a 30mm gun is successfully simulated in its computation.
