Abstract
The purpose of the present study is to gain a better understanding of boiling mechanisms in porous media with forced flow. The heat transfer and boiling of a liquid in a porous medium were studied using a vertical parallelpiped box filled with stacked spheres and heated on both sides, with the fluid flowing from bottom to top within which temperature and pressure were analyzed. The experimental analysis based on the evaluation of temperature over space and time revealed three distinct zones, corresponding to the different states of the fluid: a liquid zone Z{sub I} near the column inlet, a two-phase zone Z{sub d}, and a vapor zone Z{sub v} near the outlet. The temperature in the two-phase zone is seen to decrease, forming an N-shaped curve, probably resulting from combined flow and phase-change effects. The boundaries of the zones were determined with great precision using the temperature fields. 10 refs., 4 figs.
