Abstract:
We prove the existence of wave front solutions to a system of partial differential equations
that models the transport and accretion of suspended particles in porous media. The
model includes a variable porosity that depends on the volume of immobile particles
retained through filtration. We also examine an initial boundary value problem associated
with these equations and use singular perturbation to obtain an approximation in the
case the particle concentration is small. A local existence theorem of the leading order
approximation completes the work.
