1)  liquid film evaporation
液膜蒸发
1.
The results denote that the sand layer can greatly enhance heat transfer in high temperature region because it changes film boiling to liquid film evaporation in the sand layer.
在高温金属面上覆盖砂层后,可将高温面上的膜沸腾转化为砂粒表面的液膜蒸发,从而大幅度提高表面换热系数,强化冷却能力。
2)  thin film evaporation
薄液膜蒸发
1.
Analytical prediction of radial dryout point for thin film evaporation in heat pipes with micro-groove evaporator;
热管微槽蒸发器薄液膜蒸发的径向干点预测分析
3)  non-evaporation film
非蒸发液膜
1.
The numericalresults showed that along the extensive meniscus liquid film based on the grooved surface, disjoiningpressure is responsible for the non-evaporation film region.
数值模拟结果表明,在蒸发扩张半月形液膜中,非蒸发液膜区域液膜形状主要取决于分子膨胀压力;在薄液膜区域与非蒸发区域的连接处存在着一个强烈的蒸发点,这是膨胀压力和表面张力共同作用的结果;在本征半月形液膜区域压力梯度几乎完全取决于表面张力,因而在该区域内液膜形状可以假定为圆弧形状。
4)  microfilm evaporating
微液膜蒸发
1.
From analyzing the boiling heat transfer mechanism—the microfilm evaporating mechanism, we consider that the enhancement boiling heat transfer by narrow channels is actually to enhance the microfilm evaporating process and by enlarging the area of the microfilm the boiling heat transfer could be enhanced.
从核沸腾传热的微液膜蒸发机理出发,通过分析认为:利用窄通道强化沸腾换热,实质是对液膜蒸发过程的强化,并指出扩大微膜面积可强化沸腾换热;针对窄通道沸腾换热临界热负荷小的事实,提出了可通过及时补液的克服方法。
5)  Evaporating Thin Film
蒸发薄液膜
1.
Flow and heat transfer characteristics near the solid-liquid interface of an evaporating thin film in a microchannel was investigated using an augmented Young-Laplace model and the kinetic theory.
基于扩展Young-Laplace方程和动力学理论研究微通道中蒸发薄液膜区固液界面附近流动和传热特性,考虑压力特征、壁面滑移和温度跳跃建立物理模型。
6)  thin film evaporator
液膜蒸发器
补充资料:液膜蒸发器
分子式:
CAS号:

性质:又称液膜蒸发器,主要由竖式列管蒸发器构成。料液预热至沸点左右,自管顶或底部进入,蒸气带动料液自上而下(降膜式蒸发器falling film evaporator)或自下而上(升膜式蒸发器climbing film evaporator)或上下同时(升降膜式蒸发器climbing-falling film evaporator)成膜流动。液面达管长1/4~1/5。料液只通过加热管一次而不作循环。特点是成本低,料液停留时间短(仅数秒)、效率高;但器身长,不利于清洗和更换。适用于蒸发热敏性大和易起泡的溶液。
