NEW MODELING APPROACH FOR HEAT AND MASS TRANSFERS DURING SORPTION PHENOMENA IN A PLANE ADSORBER
要約
A model approach for heat and mass transfers during gas sorption by a zeolite bed is developed. The mathematical modeling is based on assuming the bed to be formed with three phases-solid, liquid, and gaseous. The classical finite volume method is used to numerically solve the differential set of governing macroscopic equations. Numerical results provide us the time-space evolutions of temperature and moisture content. A comparison between results obtained with a three-phase model versus those obtained with a two-phase model is performed and discussed. A comprehensive analysis of the influence of the bed porosity and the grain porosity on the average reduced moisture content and average reduced temperature is also investigated.
