进水温度对汽液两相流激波升压特性影响的实验研究

Experimental Study of the Influence of Inlet Water Temperature on the Shock Wave Pressure-rise Characteristics of Steam-water Two-phase Flows

采用实验方法研究了进水温度对汽液两相流激波升压特性的影响。实验采用供热机组的工业抽汽 ;由蒸汽喷嘴、混合腔及相应的阀门和管道组成汽液两相流激波升压装置。实验发现存在一个临界进水温度 ,当进水温度大于该临界值后 。

Through the use of an experimental method the influence of inlet water temperature on the shock wave pressure-rise characteristics of steam-water two-phase flows has been investigated. During the tests steam was extracted from a cogeneration plant to serve as the power source. A shock-wave pressure-rise device of the two-phase flow is composed of a steam nozzle, a mixing chamber and relevant valves and piping. An inlet water critical temperature has been discovered in the course of the tests. If the inlet water temperature is greater than the critical value, the pressure-rise characteristics of the above-cited pressure-rise device will decrease dramatically.
