Abstract
Subgrid modeling of a filtration flow of
a fluid in an inhomogeneous porous
medium is considered. An expression for
the effective permeability coefficient
for the large-scale component of the
flow is derived using the scale-
invariance hypothesis. The model
obtained is verified by numerical
simulation of the complete problem.
