All investigators in mass transfer assumed plug flow of gas in packed beds . 所有传递问题的研究者都假定在填充床层中的气体为活塞流。
3.
These findings show that flow in fluidized beds lies squarely between the extremes of plug and backmix flow . 这些结果说明了流化床内流动恰好位于活塞流与返混流两个极端之间。
4.
All but plug and backmix flow require rather sophisticated mathematical analysis to yield the necessary information . 除了活塞流与返混流之外，其它都需要比较深的数学分析，才能获得必要的资料。

A novel model for residual fluid catalytic cracking process ( rfcc ) is proposed . it divides the whole reactor into two part : the riser as ideal pipe flow reactor and the sett - ler as ideal cstr . the model contains six lumps reaction kinetics with serial and parallel network 通过将实际装置中发生裂化反应的提升管和沉降段反应器分别考虑为理想的活塞流反应器和连续搅拌式反应器，建立了简化的渣油催化裂化反应6集总组分的串行和并行反应动力学网络模型。
