低温毛细抽吸两相流体回路(CCPL)极限特性分析

HEAT TRANSFER LIMITS OF CRYOGENIC CAPILLARY PUMPED LOOP(CCPL)

分析了CCPL的极限特性 ,包括毛细限、沸腾限、粘性限、携带限和蒸气压限 ,计算结果表明影响CCPL传热能力的极限主要为毛细限和沸腾限。另外 ,讨论了影响毛细限的主要因素 ,为CCPL的设计和运行提供了依据。

The heat transfer limits of the cryogenic capillary pumped loop (CCPL) including capillary limit, boiling limit, viscous limit, entrainment limit and vapor tension limit are calculated to analyze the effects of these limits on the performance of CCPL. The calculated results reveal that the main affecting factors of the heat transfer characteristics of CCPL are capillary limit and boiling limit. In addition, the factors of affecting capillary limit are discussed. The present study provides a basic for the design of CCPL.
