| 摘 要： | 研究低温液体水下直接排放的传热问题，根据传热学的基本理论对传热过程进行分析与简化，分析此传热过程的特性，建立近管口水域结冰过程中温度场模型．利用此模型可计算不同的排放速度、管径等条件下的冰层生长速度，估算不同排放条件下冰层的生长状况．模型的计算结果可对进一步研究低温液体的水下顺利排放和管口除冰装置设计提供参考．

| Abstract: | The direct drainage of cryogenic liquid was studied. According to basic heat transfer theory the heat transfer process were analyzed and predigest. The characteristics of the heat transfer process were analyzed. A model calculating temperature field in the course of freezing close by orifice was presented. With the model the ice layer growth speed on different conditions such aduct diameter and emission speed were calculated. Estimate how the ice layer grow on different emission conditions. The results are helpful for further research of cryogenic liquid smoothly underwater emission and orifice deicer design. |
