| Abstract | ||||
| The theoretical model of heat and mass transfer during laminar two phase (air-water) flow along a flat plate is carried out. The governing continuity and energy equations with its boundary conditions are written for the free stream of two phase flow , the air water droplets mixture boundary layer and the water film over the plate. The equations are given for determining;the mass flux of water evaporation from film surface, the convective heat flux and the mass flux of droplets depositing on the flat plate. The analysis shows high flux resulting from the superposition of the film evaporation process from the plate surface and the heat transfer by convection. The convective heat flux appears higher than during dry air flow due to the enhancement effect of the droplets. Experimental work is carried out. The comparison between the results obtained in the theoretical model and those obtained from the experimental results is presented and it was found an agreement. | ||||
