摘要：

The aim of this paper is to develop a macroscopic model for a passive solute transport in a heterogeneous medium, consisting of impervious solids periodically distributed in a porous matrix. In the porous part, the flow is described by Darcy's law. The macroscopic equations governing the average concentration field in the equivalent medium as well as the macroscopic parameters are obtained. A homogenization technique is used. The case of small concentration of the solid inclusions is analyzed. (C) Academie des Sciences/Elsevier, Paris.
