| 英文摘要 | In order to improve the understanding of the heat transfer mechanism in a two-phase closed thermosyphon loop with a liquid heat transfer agent (TPCTLL), a visualization experiment has been conducted to investigate the hydrodynamic flow in two loops with filling ratios of 90% and 95%, respectively. In this experiment, the bubble growth at the startup stage and the slug flow patterns at the steady stage have been observed by a digital high-speed camera. It is shown that the first generated bubble grew to the maximum size within 35 ms in tested loops; and the bubble rising velocity in the loop with the filling ratio of 90% was 0.35 +/- 0.05 m/s. In comparison with single-phase closed thermosyphon loops (SPCTLs), the liquid circulation in TPCTLLs is accelerated by vapor bubbles. Thus TPCTLLs can achieve a better thermal performance than SPCTLs. |
