Abstract

The paper presents constructed two-layer model of the heat and mass transfer during condensation of saturated vapor on a horizontal half-tube placed in a microporous medium. Analytical solutions for film thickness have been found for conditions of hydrophilicity and hydrophobicity of the microporous medium. It is shown that in case of the effect of capillary forces on heat and mass transfer, these effects are manifested in thinning of the film due to suction for the hydrophilic microporous medium and high film flow velocity along the surface of the half-tube for the hydrophobic medium.
