2-D Numerical Analysis of Fin Efficiency on Straight Rectangular Fin with Combined Heat and Mass Transfer

Abstract:

An analysis was carried out to study the efficiency of straight rectangular fin with combined heat and mass transfer. Numerical solutions are obtained for fin efficiency with SOR method when the fin surface is dry, fully wet and partially wet. The effect of fin parameters including the ratio of fin width and fin thickness to fin length as well as Bix on fin efficiency were also investigated. It is found that fin parameters shows impressive effect on 2-D fin efficiency, and the critical air relative humidity becomes closer to air saturated humidity when Bix increases.
