Heat and mass transfer and hydrodynamics of liquid evaporation in contact apparatus with a porous packing

The evaporation of a saturated porous layer inside an inclined airflow channel

“…In an alternative approach, some researchers utilized a porous structure composite for the plate in the flow channel to provide a large contact area, thereby increasing the heat and mass transfer (Zhao, 1999;Diky et al, 1996). Zhao (1999) studied coupled heat and mass transfer in a stagnation point flow of air through a heated porous bed with liquid film evaporation.…”

“…In establishing the analytical solution, it was assumed that the liquid layer was very thin and stationary, and the air stream was idealized as having a stagnation point flow pattern. Diky et al, 1996 carried out an experimental investigation into liquid film evaporation in a heated air steam in a contact apparatus with a porous packing. From the discussions above, it appears that the literature lacks theoretical investigations into the feasibility of utilizing porous materials to enhance the heat and mass transfer performance in falling liquid evaporation.…”
