2021-5-5  Then there exist infinitely many “mixing solutions” starting with the inital data of Muskat type given by \(\Gamma (0)\) (in the fully unstable regime) for the IPM system. Remark 1.2. The existence of such mixing solutions was predicted by Otto in . In this pioneering paper, Otto discretizes the problem and present a relaxation in the ...

Degraded mixing solutions for the Muskat problem

We prove the existence of infinitely many mixing solutions for the Muskat problem in the fully unstable regime displaying a linearly degraded macroscopic behaviour inside the mixing zone. In fact, we estimate the volume proportion of each fluid in every rectangle of the mixing zone. The proof is a refined version of the convex integration scheme presented in [DS10, Sze12] applied to the ...

Rayleigh-Taylor breakdown for the Muskat problem with ...

The Muskat problem models the evolution of the interface between two different fluids in porous media. The Rayleigh-Taylor condition is natural to reach linear stability of the Muskat problem. We show that the Rayleigh-Taylor condition may hold initially but break down in finite time.

Solutions of the problem are unstable to small-wavelength disturbances, and there is evidence that the problem is ill-posed.

In this paper we consider the Muskat problem describing the motion of two unbounded immiscible fluid layers with equal viscosities in vertical or horizontal two-dimensional geometries. We first prove that the mathematical model can be formulated as an evolution problem for the sharp interface separating the two fluids, which turns out to be, in a suitable functional analytic setting ...
