Homogenization Methods for Porous Media Flows
Abstract: This project involves the study of fluid flows
through porous media whose permeability may be a rapidly-varying
function of space. The understanding of such fluid flows are important
in emerging technologies for remediation of porous media systems
contaminated by nonaqueous phase liquids. A homogenization procedure
provides both a leading-order description and a means to identify
explicit correction formulas that can be processed and compared with
full numerical simulations. In this presentation we assess a new
asymptotic correction formula for the porous media equation, a
nonlinear partial differential equation describing the fluid motion of
a gravity current in heterogeneous porous media, in an effort to obtain
a uniformly-valid correction formula for the leading-order homogenized
solution.
