Effect of Anionic Surfactants on the Oil–Water–Rock Interactions by an Improved Washburn Method
MoleculesThe complex and variable structure of subsurface oil reservoirs as well as the small pore throat size of reservoirs make it extremely important to investigate the effect of oil–water–rock interactions for enhancing oil recovery. In this paper, the powder

Analytical and numerical stability analysis of Soret-driven convection in a horizontal porous layer [PDF]
, 2007 We present an analytical and numerical stability analysis of Soret-driven convection in a porous cavity saturated by a binary fluid. Both the mechanical equilibrium solution and the monocellular flow obtained for particular ranges of the physical ...

The instability of fronts in a porous medium [PDF]
Communications in Mathematical Physics, 1983 We use a random choice numerical method to analyze the instability of a front separating two fluids in a porous medium. We observe a linear instability and a catastrophic finite amplitude instability. A qualitative analogy with problems involving a transition to turbulence is pointed out.
