Simultaneous heat and mass transfer with phase change in a porous slab

Abstract Simultaneous heat and mass transfer with phase change in a porous slab has been analytically investigated. Two spatially-steady regimes, corresponding to immobile and mobile condensate, are discovered. Closed-form analytical expressions for the temperature, vapor concentration, condensation rate and liquid-content distributions as well as the location of the condensation region for each of the two regimes is obtained.
