Deep bed filtration with multiple pore-blocking mechanisms

P. 1-6.
Liudmila Kuzmina, Osipov Y.

A one-dimensional model for the deep bed filtration of a
monodisperse suspension in a porous medium with variable porosity and
permeability and multiple pore-blocking mechanisms is considered. It is
assumed that the small pores are clogged by separate particles; pores of
medium size, exceeding the diameter of the particles, can be blocked by
arched bridges, forming stable structures at the pore throats. These poreblocking
mechanisms - size-exclusion and different types of bridging act
simultaneously. Exact solutions are obtained for constant coefficients, on
the concentrations front and at the porous medium inlet.
