falling film

基本解釋

The purification principle and method of technical naphthalene by melt crystalization, especially the falling film crystalization are introduced in this paper.
本文介紹了熔體結(jié)晶法，特別是降膜結(jié)晶法提純工業(yè)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離子鍍鉻、氮化鈦和化學處理水平鋁管外表面的降膜傳熱熱性。
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.
將傳質(zhì)方程引入到垂直管降膜蒸發(fā)傳熱模型中，求解時考慮了徑向速度、質(zhì)量擴散系數(shù)和膜厚變化對傳熱的影響。

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.

降膜
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.
水平管內(nèi)凝結(jié)是多效蒸餾水平管降膜蒸發(fā)器內(nèi)的主要傳熱過程之一,對蒸發(fā)器傳熱效果、對蒸發(fā)器的熱力計算起著決定性的作用。

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.
但實驗結(jié)果表明僅靠改變布液器結(jié)構(gòu)難以消除制冷劑分布不均的現(xiàn)象，而且采用自然噴淋的液體噴淋密度也不夠大，因此本文對兩種微翅片管和光滑管進行強制噴淋式水平降膜蒸發(fā)器傳熱性能研究，為吸收式熱泵系統(tǒng)中蒸發(fā)器的改進提供依據(jù)。
