WATER THERMOMIGRATION IN THE POROUS MEDIA
摘要
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.
