Résumé

We study the coupled phenomenon of heat and mass transfer in the unsaturated porous media. Earlier studies show that moisture moves from the hot side to the cold one and thus causes a gradient of the degree of humidity in this direction when both the hot and cold sides of the sample are impermeable. Whe have experimentally show that, in the case when sides are permeable, the humidity profile always presents a maximum in the middle of the sample. The value of this maximum decreases in time until the complete drying of the medium.
