摘要
在不同的混合腔喉部直径、喷嘴前蒸汽压力、进水流量下 ,实验研究了汽液两相流激波升压装置的特性 .实验结果表明 ,汽液两相流激波升压的最大无量纲升压系数为 2 .4 ;混合腔喉部直径增大 ,其升压效果下降 ;引射率及蒸汽压力增加 ,其无量纲升压系数都将增大 .这些结论对汽液两相流激波升压装置的进一步研究及应用具有一定的意义 .
The performance of the steam water two phase flow shock wave injector is studied experimentally. The injector system includes steam nozzle, mixturem chamber and the corresponding valves and tube. The characteristics of the injector are investigated by varying throat dimension of the mixture chamber, the initial steam pressure before the nozzle and the inlet water flux. The maxium dimensionless pressure lifting coeficient in the experiment is 2.4. The outlet pressure increases with the inlet steam pressure and the inlet water flux, but decreases with the throat diameter of the mixing chamber.
