Heat Transfer Characteristics for A Fin Exposed to Fully Wet Air

A numerical method for two types of longitudinal tapered fins exposed to fully wet air conditions have been studied using grid generation methods. The study included the effect of relative humidity on the temperature distribution for a fully dry fin and fully wet fin at different relative humidity of 0, 50, 75 and 100%. Fin effectiveness, fin efficiency and heat flow have been calculated at a relative humidity of 10, 20, 30, 40, 50 and 100% and fin length varies from 0.01 to 0.1 m. This study shows that the fin efficiency and fin effectiveness in dry fin are found to be larger than those in the wet fin and the temperature gradient at the tip of a ful006Cy wet fin is smaller than that in the dry fin.
