摘要
在低液速区操作的滴流床，由于存在部分润湿现象，操作特性与全润湿滴流床不同，机理也更复杂。本文综述了此类反应器研究的现状和存在的问题。近年来，在润湿机理和床层两相流动的描述方面取得了较大进展，本文讨论了它们对反应器建模的启示。
Due to the existing of partially wetting phenomenon,the paritally wetted trickle bed operated under low liquid velocity region features differently from those wholly wetted ones,and the mechanism is also more complex.In this paper,the advances and the problems to be solved are reviewed.The recent progresses are encouraging on the description of wetting mechanism and multi—phase flow in trickle bed,the influences from which on the modeling of partially wetting trickle bed reactor are discussed.
