Progress on CFD simulation for mass transfer optimization of membrane process
摘要
Abstract
Recent research progress on how CFD helps contribute to mass transfer in membrane process respectively from four different aspects,membrane module,membrane structure,operation conditions and process coupling were reviewed in this paper. It pointed out that the superiority of CFD simulation for mass transfer optimization of membrane process is widely proved not only in the design and modification of feed spacer and membrane structure,but also in the visualization researches of pulsating flow,two-phase flow and mechanical vibration in different fields(flow,concentration and temperature). In addition,CFD simulation was employed to illustrate mass transfer mechanism of coupling membrane with other dynamic systems and found it a promising way to increase the shear rate of boundary layer,which can further result in better separation efficiency. However,it is still difficult for CFD simulation to get both high accuracy and low computation expense. On the other hand,current material processing technology cannot satisfy the simulation study,which hindered the practical application of CFD. Future researches will focus on combining various optimization methods and applying emerging detection and manufacturing technologies to make up the deficiency in experiment and thus,achieve new computational models which fit the practical situation better.关键词
