采用逆流中空纤维膜管束(HFMTB)进行液体除湿。研究了光纤之间的相互作用对HFMTB中共轭输运现象的影响。在管束中，液体干燥剂在纤维内部流动，而空气以逆流方式在纤维之间流动。热量和水分通过薄膜有效地交换。考虑了两种固定填充的排列，即串联排列和交错排列。选择由两根纤维组成的两个具有代表性的单胞，即纤维内部流动的液体干燥剂和纤维间流动的气流作为计算区域。基于共轭的传热传质边界条件，将管侧、膜侧和壳侧的流体流动和传热传质的控制方程耦合求解。然后，考虑相邻纤维之间的相互作用，得到了单胞中的局部和平均Nusselt数和Sherwood数，并进行了分析和实验验证。将计算结果与自由面模型计算结果进行了比较。
A counter flow hollow fiber membrane tube bank (HFMTB) is employed for liquid desiccant air dehumidification. The effects of the fiber-to-fiber interactions on the conjugate transport phenomena in the HFMTB are investigated. In the tube bank, the liquid desiccant flows inside the fibers, while the air flows between the fibers in a counter flow arrangement. Heat and moisture are effectively exchanged through the membranes. Two regularly populated arrangements, in-line and staggered, are considered. Two representative unit cells consisting of two fibers, the liquid desiccant flowing inside the fibers and the air stream flowing between the fibers, are selected as the calculation domains. The governing equations for the fluid flow and heat and mass transfer in tube side, membrane side, and shell side are conjugated together and solved based on the conjugate heat and mass transfer boundary conditions. The local and mean Nusselt and Sherwood numbers in the unit cells considering the interactions between the neighboring fibers are then obtained, analyzed, and experimentally validated. The results are compared with those calculated by the free surface model.
