汽液两相流不稳定性实验研究

EXPERIMANTAL STUDY ON UNSTABILITY OF VAPORLIQUID PHASE FLUID

针对蒸汽在过冷水中凝结时发生凝结振动，通过实验考察了汽地的振动限及影响动频率的有关因素。

Condensing vibration often takes place when the vapor goes through the pipe and condenses in the supercoo1ed water. On the basis of the unstability of the vapor-liquid phase fluid occurring in the evacuated phase changed heat exchanger,the present paper studies the unstability contained in condense-vapor pipes. The paper also investigates the bubble unstable vibration limitation and relative factors which affect the vibration and frequency.The result is of significance in engineering.
