蒸发管内汽液两相流压力降型脉动集总参数非线性分析

摘要

The pressure drop oscillation is analyzed by using a lumped parameter nonlinear model in this paper.The results show that the pressure drop type instability can be described by a second order differential equation.The effect of operation conditions on the pressure drop oscillation can be expressed by two dimensionless parameters E,η Model results agree qualitatively with experimental results.
