چکیده انگلیسی
A numerical analysis has been carried about to study the heat and mass transfer of forced convection flow with liquid film evaporation in a saturated non-Darcian porous medium. Parametric analyses were conducted concerning the effects of the porosity ε, inlet liquid Reynolds number Rel, inlet air Reynolds number Rea on the heat and mass transfer performance. The results conclude that better heat and mass transfer performances are noticed for the system having a higher Rea, a lower Rel, and a higher ε. Rel plays a more important role on the heat and mass transfer performance than Rea and ε. For the case of ε = 0.4 and Rea = 10,000, the increases of Nu and Sh for Rel = 50 are about by 33.9% and 35.3% relative to the values for Rel = 250.
