Substance transfer in a porous medium saturated with mobile and immobile liquids.

Consideration has been given to the problem of transfer of a substance in a porous medium consisting of two zones: a) with transit pores (with a mobile liquid) and b) with an immobile liquid (with bound water) with allowance for the effects of convective transfer, hydrodynamic dispersion, substance adsorption, and internal mass transfer between both zones. The fields of substance concentration, adsorption, and internal mass transfer for different cases determined by the character of adsorption and internal mass exchange have been determined. It has been established that the presence of zones with an immobile liquid significantly influences the general characteristics of substance transfer in the porous medium. [ABSTRACT FROM AUTHOR]
