CPL复合毛细芯流动性能及工质特性分析

ANALYSIS ON FLOW PERFORMANCES OF COMPOSITE WICK AND WORKING FLUID CHARACTERISTICS FOR CPL

本文分析了两相毛细泵回路(CPL)复合结构毛细芯的流动阻力特性,讨论了影响毛细芯阻力大小的主要因素,计算结果表明,复合毛细芯的流动性能比单一粒径毛细芯优越。另外,还分析了工质物理性质对CPL性能的影响,指出改善工质表面张力特性是研制高性能CPL的方向之一。

The flow performances of a composite wick for the Capillary Pumped Loop (CPL) were analyzed. The main affecting factors on the flow resistance were discussed. The calculated results revealed that flow capability of the composite wick is better than that of the mono-wick. In addition, this paper also analyzed the effect of the characteristics of working fluids on performance of wick CPL. It is obvious that the improvement on surface-tension characteristics of the working fluids is one of the main research aspects for CPL technology.
