摘要: 对气液两相非定常一元流动方程组导出了两套代数显式解析解。第一套解由时间与几何坐标的简单函数构成,比较简单明了,而且具有典型的物理意义。第二套解的表达式中包括了任意函数,实际上有无限多个解。而且此解还带有行波的形式,特别适宜用于研究有波动传递的两相流过程及用级数来表达不同的流动。

Abstract: Two sets of algebraically explicit analytical solution are derived for the partial differential equation set describing the one dimensional unsteady gas-liquid two phase flow. The first set of solution only consists of simple functions of time and geometry. The physical meaning of this analytical solution is clear and typical. The second set of solution includes arbitrary functions and is of the form of moving wave. It is specially suitable for the investigation of two phase flow in which wave transferring exists and to express different flows by series.

Key words: Analytical solution, Two phase flow, Unsteady flow
