| 摘 要： | 为研究液体推进剂在真空环境下的蒸发特性,建立了真空环境模拟试验系统。对水、饱和盐水、煤油、酒精和凝胶模拟液等工质进行了蒸发特性试验。通过控制系统实时采集了真空舱的真空度和工质温度。试验中观察到了明显的闪蒸现象。由于闪蒸的存在,工质蒸发过程非常剧烈。最后分析了不同工质在真空环境下的蒸发特性,给出了部分工质的闪蒸参数。

| Abstract: | A simulant vacuum system was built to study evaporation characteristics of liquid propellants in vacuum. Water, saturated brine, kerosene, alcohol and simulant gelatin were studied in the experiments. The vacuum pressures and temperatures of propellants were recorded during the tests. The substance vaporized explosively due to flash evaporation, which could be observed evidently. The evaporation characteristics of different substances was analyzed and parameters of flash boiling was calculated. |
