膛内双流体模型的平均场守恒方程

Average Field Conservation Equations for Two—fluid Model in Interior Ballistics

本文引进连续介质平均的概念,建立起参量平均值的微分与参量微分平均值所满足的关系式,并以单相场方程与边界突跃条件为基础,推得描述膛内循环过程细节的双流体模型守恒方程组.

A concept of continuum is introduced.The correlations between the differentiationof parameter average and the average of parameter differentiation are established.Based onthe equations of one—phase field and the jump conditions of boundary,the conservation equa-tions for two—fluid model describing the detail of interior ballistic cycle are derived.
