✦ Synopsis

The interactions between two particles and between one particle and a rigid boundary are examined to study the effect of particle concentration on partitioning, stress and flow in microporous media. Because the particle-particle and particlewall interactions occur over comparable length scales, their effects are not additive and lead to non-uniform particle concentration and stress ("surface pressure") in the vicinity of the boundary_ A particle concentration gradient parallel to the boundary creates a gradient in surface pressure which drives a viscous flow of the solvent toward regions of higher concentration. Such flows are termed "osmosis". and the effect of particle interactions is to reduce the osmotic velocity. II.
