INITIAL STAGE OF IMPREGNATION AND EXTRACTION IN MODELING A POROUS MEDIUM BY A TWO-CONTINUA MODEL

The initial stage of impregnation (extraction) is investigated on the basis of the model of mass transfer in a porous material consisting of two continua (bidisperse model) with its specifi cs of diffusion processes in each of them. Particular emphasis was placed on considering asymptotic (analytical) representations of the solutions of corresponding problems under typical additional conditions, in particular, for a body of fi nite dimensions.
