falling film

基本解释

The purification principle and method of technical naphthalene by melt crystalization, especially the falling film crystalization are introduced in this paper.
本文介绍了熔体结晶法，特别是降膜结晶法提纯工业萘的原理和方法。
Seawater falling film evaporation heat transfer and anti-fouling characteristics were investigated on ion-plated chromium, TiN and chemically treated aluminum tubes.
考察了淡水和海水在离子镀铬、氮化钛和化学处理水平铝管外表面的降膜传热热性。
The mass transfer equation was introduced into heat transfer model of falling film evaporation. The radial velocity, mass diffusion coefficient and variation of film thickness were taken into account.
将传质方程引入到垂直管降膜蒸发传热模型中，求解时考虑了径向速度、质量扩散系数和膜厚变化对传热的影响。

Eric Rohmer constructed his latest film, from 2004, on his old theme: the danger of falling for a false love while awaiting a real one.

Condensation in horizontal tubes is one of the primary heat transfer processes in the falling film evaporator for multi-effect distillation, and it has decisive effect on heat transfer effect and caloric calculation of evaporator.
水平管内凝结是多效蒸馏水平管降膜蒸发器内的主要传热过程之一,对蒸发器传热效果、对蒸发器的热力计算起着决定性的作用。

But the experimental result shows that the unequal distribution can be resolved by the improvement of the distributor. So the paper investigates the heat transfer characteristics of falling film evaporation on horizontal microfinned tubes with forced spray cycle.
但实验结果表明仅靠改变布液器结构难以消除制冷剂分布不均的现象，而且采用自然喷淋的液体喷淋密度也不够大，因此本文对两种微翅片管和光滑管进行强制喷淋式水平降膜蒸发器传热性能研究，为吸收式热泵系统中蒸发器的改进提供依据。
