Abstract | Evaporation - a key process for water exchange between soil and
atmosphere - is controlled by internal water fluxes and surface vapor
fluxes. Recent studies demonstrated that the dynamics of the water flow
in pore corners and thick-film flow on the rough pore-solid interface
determine the time behavior of the evaporation rate. A comprehensive
experimental study of the combined effect of corner flow (CF) and
thick-film flow (TFF) on evaporation is lacking. Herein, we present a
comparative micromodel study of the evaporation process using 2D-porous
media, which exhibit the same stochastic pore structure, but different
degree of surface roughness (silicon micromodels with smooth surface;
glass-ceramic micromodels with rough surface). Our study proves both
experimentally and theoretically that surface roughness and wettability play a key role for the time- and temperature behavior of the evaporation process. We found a similar ![]() |
