Ni. Gamayunov, SOME PROBLEMS OF SORPTION AND DESORPTION DYNAMICS IN BIPOROUS MEDIA, Journal of applied mathematics and mechanics, 57(4), 1993, pp. 659-667
Solutions of problems of mass transfer in a semi-infinite biporous med
ium in which convective transfer of a liquid or gas occurs in the macr
opores and molecular diffusion and sorption (desorption) in the transv
erse direction takes place in the micropores of sorbent (ionite) grain
s are presented. Solutions of analogous axially symmetric problems wit
h impulsive and constant supply of the substance being absorbed into a
cylindrical cavity are also obtained.
