内弹道非线性发展方程的定解条件:1.运动边界条件的设计

THE PARTICULAR SOLUTION CONDITIONS OF INTERIOR BALLISTICS NONLINEAR DEVELOPING EQUATIONS A. DESIGN OF MOVING BOUNDARY CONDITIONS

本文主要论述两相流内弹道方程组数值分析中动边界设计方法。结合若干实例,介绍边界设计中采用“特征线”法的局限性及其“控制体”方法的优点。

This paper mainly deals with the design method of moving boundary conditions in the numerical analysis of the interior ballistics two-phase flow equations. In the light of some practical examples, this paper discusses limitations of the characteristics method and advantages of the control volume method in numerical treatment of boundary conditions.
