热管蒸发段内质量注入对蒸汽流动影响的理论分析

THEORETICAL ANALYSIS OF EFFECTS OF MASS INJECTION ON VAPOR FLOW IN HEAT PIPE

从蒸发段质量注入角度着手，综合各方面的因素，分析了热管蒸汽温度、温差、压力、压力降及传热量的变化，得到了径向雷诺数Ｒｅｒ与蒸汽流动参数变化的曲线分布，研究表明热管的不等温性，蒸汽的压力损失和传热极限与质量注入多少有关。

In this paper,the vapor temperature,temperaturedifferential,pressure,pressuredifferential and heat transfer rate are disscussed from the point of the mass injection of the evaporator and considering all factors.The relation curves of radial Reynolds number (Rer)with the vapor parameters are provided.It is shown that the vapor nonisothermality,pressure loss and heat transfer limit rates depend on the mass injection.
