重力热管弹状流工况的简化分析

THE ANALYSES ON THE PERFORMANCE OF THE SLUG FLOW IN GRAVITY HEAT PIPES

对重力热管弹状流工况进行简化分析，定量描述工业热管工作过程中蒸发段内汽泡的喷涌现象，给出液塞在弹状汽泡载带下的提升高度Ｌ５和体积流量与两端压力间的定量关系．

This paper presents the detailed analyses and simplifications on the slug flow regimes inside gravity heat pipes. The slug flow in the evaporation section of industrially used heat pipes is quantitatively described. The result reveals the explicit relation of the lift length of the liquid slugs carried by vapour plug with volumetric flow rate and pressures at both ends of pipes.
