| 摘 要： | 研究了低温液体的水下直接排放问题，分析了低温液体与水之间的传热过程及其特性，给出了一种处理问题的方法，建立了超临界液一液传热模型、动态液-(气-)液传热模型，不同的传热模型适用于不同的排放环境压力(即水压)，根据动态液-(气-)液传热模型进行了初步的计算，计算结果表明，在一定水压下，选择适当的低温液体初始状态及排放口尺寸，完全可以维持一段低温液柱，实现低温液体的顺利排放。

| Abstract: | The cryogenic liquid drained directly into water was studied. The process and characteristics of heat transfer between cryogenic liquid and water were analyzed. The paper presented a simplified method. The model of liquid-liquid heat transfer in supercritical environment and the model of liquid-(gas-) liquid heat transfer in non-supercritical environment were established. Different models were applied to different environment pressure (water pressure). The result of calculation based on the model of liquid-(gas-)liquid heat transfer in non-supercritical environment showed that the cryogenic liquid in proper condition would be drained successfully. |
