山东大学硕士学位论文 摘要 HFC-134a作为一种广泛认可在绿色环保潜在替代制冷剂,分析其 在各种工况下的换热情况具有很重要的意义。由于过冷沸腾时液体并 没有完全达到饱和温度,而沸腾换热的传热系数又大大高于单相对流 换热系数,可以很好地强化传热,降低传热温差,提高传热效率。过 冷沸腾处于流动沸腾的起始阶段,其流动...
This paper focuses on analyzing the distributions of pressure, temperature, relative velocity, and bubble volume in a fluid self-lubricating centrifugal pump with R134a refrigerant under different operating conditions. The objective is to obtain insights into the changing patterns of flow characteristics ...
