摘要：

In order to study the effect of the pore size distribution and flow segregation on dispersion in a porous media, we consider the dispersion of solute in an array of parallel pores. Equations are obtained for the dispersion coefficient in laminar and turbulent flow, as a function of the particle Peclet number. The theory fits quite well cumulative experimental data from various researchees in Peclet number range from 10-3 to 106. The model also predicts some trends, backed by experimental data, regarding the effect of particle size, particle size distribution and fluid velocity on dispersion. © 1979.
