IN A VERY NON-HOMOGENEOUS
Professor of the Tel-Aviv University
1999 visiting prof. at
Fluid flow in porous media is a main component of
many natural and technological
processes, like an oil and water recovery. The porous medium is usually
and this nonhomogeneity is sometimes very high: the local permeability
may vary within
some number N of decimal orders, where N may be big. I am going to
describe the properties
of the flow field in this extreme case. The velocity and pressure fields
described in terms of geometry and topology of the permeability field.
The problem is
solved by probabilistic methods.
The talk is self-contained, and no background is
