PRELIMINARY ANALYSIS OF TWO-PHASE CIRCULATION IN A CAPILLARY PUMPED LOOP
-
摘要: 本文初步分析研究了在微重力或失重情况下毛细泵环中两相循环回路的稳态流动情况,提出了基于力平衡的两相循环回路一维稳态数学描述。从计算结果得出了最佳有效毛细孔半径等结论。Abstract: The steady two-phase circulation in a capillary pumped loop(CPL)under microgravity or non-gravity conditions is analyzed preliminarily in this paper.Based on force balance,one-dimensional mathematical description about two-phase fluid flow in CPLis provided.Two practical examples are calculated,and some useful conclusions are obtained,including the optimal effective capillary radius,its calculational method and change tendency with working temperature etc.
