摘要
本文研究以蒸汽为工作流体的引射式增压装置,蒸汽引射水后利用自身的动力使水得到增压,使引射器出口水的压力超过入口蒸汽的压力。同时,由于蒸汽的凝结实现换热,水温得以提升,该装置又可视为一个直接接触式换热器。增压的特点使该装置具有特殊的应用前景,如可用于核电的非能动安全系统,然而有关设计的研究却较少。本文对基于两相流激波的引射式增压装置进行研究,给出其设计方法,并进行了试验研究,得到了增压效果。试验结果与设计结果吻合,说明了设计的可靠性。
Injector with pressure rise was studied with the steam as the working fluid.The water injected by the steam gains higher pressure under the driven of the steam power.The outlet water pressure is higher than the inlet steam pressure.Meanwhile,the temperature of the water rises when the steam condenses and heat is released.So the injector can be looked on as a direct contacted heat exchanger.The character of pressure rise makes it possible to use the injector in some special field, such as the nuclear passive...
