Rayleigh–Taylor instability of immiscible fluids in porous media

The time development of an interface separating two immiscible fluids of different densities in heterogeneous two-dimensional porous media is studied. The governing equations are simplified with the help of approximate Green’s functions which allow computation of the shape of the interface directly without resolving the fluid flow in the entire domain. The new formulation is amenable to numeric...

Ablative Rayleigh-Taylor Instability: Compressibility Effects

Rayleigh-Taylor instability of an ablation front is one of the main issues that determine the performance of an inertial fusion target. In the last few years we have improved our understanding of this instability thanks to several analytical and semianalytical models developed mainly for the regime of relatively short perturbation wavelength λ (kL0 << 1 and k=2π/λ is the perturbation wave numbe...

On Fingering Instability in Immiscible Displacement

Departing from the classical Buckley-Leverett theory for two-phase immiscible flows in porous media, a reduced evolution equation for the water-oil displacement front is formulated and studied numerically. The reduced model successfully reproduces the basic features of the finger-forming dynamics observed in recent direct numerical simulations. PACS numbers: 47.20.Gv, 47.20.Ky, 47.20.Ma

Infiltrations in Immiscible Fluids Systems

In this paper we prove a certain regularity property of configurations of immiscible fluids, filling a bounded container Ω and locally minimizing the interface energy ∑ i<j cij‖Sij‖, where Sij represents the interface between fluid i and fluid j, ‖ · ‖ stands for area or more general areatype functional, and cij is a positive coefficient. More precisely, we show that, under strict triangularity...
