Paper Title:
Experimental and Analytical Study of Contaminant Transport Resulting from Dissolution of a Flat Surface Buried in a Packed Bed
  Abstract

The present work describes the mass transfer process between a moving fluid and a slightly soluble flat surface buried in a packed bed of small inert particles with uniform voidage, by both advection and diffusion/dispersion. Numerical solutions of the differential equations describing solute mass conservation were undertaken to obtain the concentration profiles, for each concentration level. A simple mathematical expression that relates the dependence between concentration and axial distance is proposed to describe the approximate size of the diffusion wake downstream of the reactive solid mass.
