ABSTRACT
3-D laminar model of a rectangular porous channel with high thermal conductivity and constant wallheat flux is chosen to investigate the enhancement of heat transfer when used in conjunction with thephase change material slurry. Numerical simulations for various wall heat fluxes and inlet velocitiesare carried out. The slurry consists of microencapsulated octadecane (C18H38) and water. The heattransfer coefficient of the porous channel with pure water and with micro-encapsulated phase changematerial are calculated and compared. The effect of porosity and permeability of the porous mediumon the heat transfer coefficient while using slurry of phase change material are studied. The resultsshow that the heat transfer coefficient of the porous channel can improve by introducing phasechange material slurry, but only under certain heat fluxes, inlet velocities, and porous mediaproperties.
