摘要: As amajor configuration of membrane elements,multi-channel porous inorganicmembrane tubeswere studied by means of theoretical analysis and simulation. Configuration optimization of a cylindrical 37-channel porous inorganic membrane tube was studied by increasing membrane filtration area and increasing permeation efficiency of inner channels. An optimal ratio of the channel diameter to the inter-channel distance was proposed so as to increase the total membrane filtration area of themembrane tube. The three-dimensional computational fluid dynamics (CFD) simulationwas conducted to study the cross-flow permeation flow of purewater in the 37-channel ceramic membrane tube. A model combining Navier-Stokes equation with Darcy's law and the porous jump boundary conditions was applied. The relationship between permeation efficiency and channel locations, and the method for increasing the permeation efficiency of inner channels were proposed. Some novel multichannel membrane configurations with more permeate side channels were put forward and evaluated.
