Asymptotic solution for deep bed filtration with small deposit

Procedia Engineering. 2015. Vol. 111. P. 491-494.
Ludmila I. Kuzmina, Osipov Y. V.

Filtering the suspension in a porous soil is important for long-term evaluation of soil strength in the construction of underground and hydrotechnical structures. A size-exclusion model of solid particle capture for a flow of suspension in a porous media is considered: particles pass freely through the large pores and get stuck at the inlet of small pores whose diameter is less than the particle size. The asymptotic solution for the concentrations of suspended and retained particles is constructed under the assumption that the limit deposit is small.
