Theoretical study of interphase heat and mass transfer in saturated porous media

摘要

Transient convective heat and mass transfer between the solid and fluid phases of a saturated porous medium has been considered in the present study. A geometrically simple model that is capable of predicting retardation of the species has been developed. The equations governing species transport in the liquid and solid phases of the porous medium are coupled due to heat and mass transfer at their interface. The species concentration in the liquid phase is determined by analytically solving the system of differential equations along with experimentally motivated values of the interphase parameter.
