Abstract (EN):
Mass transfer between a single prolate spheroid buried in a porous media and exposed
to fluid flow has been theoretically studied, for convection with molecular
diffusion. A general solution of this problem is not available analytically and two
particular cases were considered for the purpose of the present work. The analytical
steady-state solutions for the limiting cases of mass transfer with a thin concentration
boundary layer (high values of Peclet number) and the pure diffusion
regime (diffusion in a stagnant fluid) were obtained. The solution is expected to
describe the problem of mass transfer between a large soluble prolate spheroid
and the fluid flowing around it in the interstices of a packed bed, with an error of
less than 10 %.
