内弹道多维多相流壁面边界条件探讨

PROBE INTO THE WALL BOUNDARY CONDITIONS FOR MULTI-DIMENSIONAL MULTI-PHASE FLOW IN GUN

文中介绍了内弹道多维多相流壁面边界条件的几种处理方法，根据膛内流动的特点，提出了单侧差分格式处理壁面边界条件的方法。数值实践表明，该方法解决了边界点与内点是的协调关系，是一种较好的方法。

Some methods to treat the wall boundary conditions for multi-dimensional multi-phase flow in gun are persented. Based on the characteristics of flow in gun, this paper designs a one-side differenee scheme to manage the wall boundary conditions, The numerical experiment shows that this scheme can resolve the harmonious relation between boundary points and interior points, it is a better method to deal with the wall boundary conditions.
