Experimental investigation of flow characteristics in a vertical vibration two-phase loop thermosyphon

In this paper, flow characteristics of a two-phase loop thermosyphon under vertical reciprocating vibration are visually investigated with N-pentane as the working fluid. The tests performed for heating power range 20 W to 40 W, filling ratio 30 % 70%, and m?s-2, 35 Hz vibration. effect on is by comparing obtained results those acquired in static, thereby providing basis explaining heat transfer process indicate that promotes rupture liquid plug transformation annular or wavy flow. Furthermore, does not change distribution law velocity thermosyphon. However, it will reduce overheating at start-up. With an increase power, influence reduced due continuous disturbance medium
