蒸发管内汽─液两相流不稳定性线性分相模型

The Linear Separated Model of Vapor-liquid Two-phase Flow Instability in Evaporated Tubes

本文提出了描述两相流不稳定性的线性分相模型。根据分相模型运用系统控制的方法导出了描述两相流不稳定性的动态系统特征方程式。根据特征方程式的特片值就可以判断系统的稳定性，计算值与试验值基本吻合。

This paper present liner separated model describing two-phase flow instability. By means of separated model and appling system control theory,dynamic system characteristic equations of describing two-phase flow instability are derived. It can be decided system stability depending on the characteristic value of characteristic equation. The calculated results agree with the experimental data.
