一种内冷式平行板膜接触器已被提出、设计并用于液体干燥剂空气除湿。它由一系列侧进和侧出平行板膜通道（QCPMC）组成。处理空气和液体干燥剂（溶液）流通过膜分离。溶液通道内装有冷却管，带走吸收热量。溶液侧带有冷却管的复杂 QCPMC（QCPMCC）中的摩擦系数和传热系数对于结构设计和能量分析是必要的。因此，基于包含冷却管外部两个相邻膜之间的夹层域的晶胞来研究溶液通道中的层流和传热。动量和热传输控制方程与均匀壁温边界条件一起建立，并通过有限体积方法求解。然后计算平均值 (fRe) 和努塞尔数 (Num)。分析了雷诺数 (Re)、管数 (Ntube)、管外径 (douter)、管布置和管连接类型对 (fRe)mandNuma 的影响。可以发现，当douter=0.003m时，(fRe)m随着Ntube的增加而增加。然而Num随着Ntube的增加而减少。当 Ntube= 4 时，(fRe)m 随着 doouter 的增加而增加。然而，douterare 越大，Numare 越小。
An internally-cooled parallel-plate membrane contactor has been proposed, designed, and used for liquid desiccant air dehumidification. It is comprised of a series of side in and out parallel-plate membrane channels (QCPMC). The processing air and the liquid desiccant (solution) streams are separated by the membranes. Cooling tubes are installed in the solution channel to take away the absorption heat. The friction factors and heat transfer coefficients in the complex QCPMC with the cooling tubes in the solution side (QCPMCC) are necessary for the structural design and energy analysis. Therefore the laminar flow and heat transfer in the solution channel are studied based on a unit cell containing the sandwiched domain outside the cooling tubes between two neighboring membranes. The momentum and thermal transport governing equations are built up together with a uniform wall temperature boundary condition and solved by a finite volume approach. The mean (fRe) and Nusselt numbers (Num) are then calculated. Influences of the Reynolds numbers (Re), tube number (Ntube), tube outer diameters (douter), tube arrangements, and connection types of tubes on the (fRe)mandNumare analyzed. It can be found that whendouter= 0.003 m, the (fRe)mrises with an increase in theNtube. However theNumdecrease with theNtubeincreasing. WhenNtube= 4, the (fRe)mrise with an increase in thedouter. However the larger thedouterare, the smaller theNumare.
