Résumé

A parallel-plate membrane contactor with quasi-counter flow arrangement has been designed and used for liquid desiccant air dehumidification. The air and the liquid desiccant streams are separated by the semi-permeable membrane which only allow the permeation of water vapor. Heat and water vapor of the two streams are exchanged through the membrane. The three-dimensional mathematical model is built based on the unit cell, which containing a plate-type membrane and half of the channel. The momentum, energy and mass conservation equations are solved by a finite volume difference approach under the conjugate heat and mass transfer boundary conditions. The local and mean product of friction factor and Reynold, Nusselt number and Sherwood number are then obtained. Influence of entrance ratios (xin/x0) on the (ƒRe)m, Num and Shm are analyzed.
