flows as easily as a conventional organic liquid consist- ing of similar molecules, an analysis of the viscosities turns out to be rather complicated when the state

Results of experiments on the viscosity in li- the interpolation formula of Greywall and Alhers quid 4 ~ e near T1 at saturated vapour pressure (SVP) /12/.. have been

Moreover, under some regularity assumption on the initial datum u 0 , such a variational problem allows to define a weak formulation of the Hele-Shaw flow [9, 11] (see also [12] for

From these considerations, it maybe stated that replacing the Newtonian viscosity by the one of the Carreau law in order to take into account the pseudoplastic behavior of

In this paper we consider a two-phase flow problem in porous media and study its singular limit as the viscosity of the air tends to zero; more precisely, we prove the convergence
