✦ Synopsis

Abstract

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 %.

## Abstract The equations describing fluid flow and mass transfer around a sphere buried in a packed bed are presented, with due consideration given to the processes of transverse and longitudinal dispersion. Numerical solution of the equations was undertaken to obtain point values of the Sherwood
