Conjugate heat and mass transfer in a hollow fiber membrane module for liquid desiccant air dehumidification: A free surface model approach

Numerical modeling of fluid flow and coupled heat and mass transfer in a counter-cross-flow parallel-plate liquid-to-air membrane energy exchanger

“…It was also proposed that there were differences between the features of the membrane-formed parallel-plates channels and impermeable (as they called ''traditional metal-formed'') parallel-plates channels. According to [24][25][26] the fully-developed Nu number was constant along the exchanger, but its value was different from the values presented in [21,22]. Huang et al [24] showed that the Nu numbers were not similar for the two streams and the liquid desiccant had a slightly higher Nu.…”

“…The validity of this approximation has been investigated in the literature [24][25][26]. The Nu and Sh numbers were obtained from conjugate heat and mass transfer in the liquid desiccant-air energy exchangers in [24][25][26]. It was found that the real boundary condition on the membrane surface is not uniform heat (or mass) flux and it should be obtained by the solution of momentum, energy and concentration equations.…”

“…A method was suggested in [24][25][26] to determine Nu and Sh number from the real boundary condition on the membrane surface. It was proposed that the ''naturally formed'' boundary condition on the membrane surface should be obtained from the simultaneous solution of momentum, energy and concentration equations for the two fluids.…”

Solar pond powered liquid desiccant evaporative cooling

“…Researchers have proposed membrane designs such as flat plate type [82][83][84][85][86] or hollow tube fibre type [87][88][89][90]. Though the flat plate membrane type is simpler in construction, the hollow fibre membrane type promises relatively better effectiveness, due to the latter's considerable higher packing density [91].…”

Modelación y simulación computacional del proceso de evaporación osmótica

“…Aunque el flujo en el módulo real de fibras huecas no está absolutamente de acuerdo con el modelo de Happel, este se ha utilizado ampliamente para contactores de membrana (Zhang, Huang, Chi y Pei, 2012). 2 2 2 3 2 3 2 4 2 2 2 1 2 3 2 3 2 3 2 3 / / 2ln / 0 1 ( ) A la salida de la carcasa, la presión es la atmosférica y se especifica por la ecuación (42), la línea central entre las fibras se consideró una simetría axial (43).…”
