| Title: |
Immiscible two-phase
flows in porous media with discontinuous capillarities
|
Abstract
|
We consider a simplified model
for two-phase flows in porous media made of different rocks. We focus
on the effects of the discontinuity of the capillarity field. We first
consider a model with capillarity within the rocks. Then we look for
the asymptotic problem for capillarity forces remaining only at the
interface. We propose a simple modeling of oil-trapping by the mean of
non- classical shocks at the interface.
