Abstract Viscous fingering in porous media occurs when the ( miscible or immiscible ) displacing fluid has a lower viscosity than displaced fluid. For example, is observed experiments where water displaces much more viscous oil. Modelling patterns proven to be very challenging, which often been identified as being due numerical issues. However, recent paper (Sorbie et al. Transp. Porous Media 1...

The numerical investigation of the interpenetrating flow dynamics a gas injected into homogeneous porous media saturated with liquid is presented. analysis undertaken as function inlet velocity, liquid–gas viscosity ratio (D) and physical properties medium, such geometry surface wettability. study aims to improve understanding interaction between parameters involved in complex multiphase (e.g.,...

An advanced chromodynamics, Rothmann-Keller (RK) type lattice Boltzmann model (LBM) is used in this study. The new benefits from high stability and capability of independently setting the interfacial tension fluids as an input parameter. In addition, coupled with a wall-density approach to simulate hydrophilic or hydrophobic properties wall surfaces. Finally, injection wetting (non-wetting) flu...

In this work the problem of displacing a ganglion ?uid by another immiscible one in capillaries is investigated. A modeling approach developed to predict location with time. The model describes two patterns; namely, when totally exists inside tube, and advancing interface has broken through exit tube. valid for case which wetting as well it nonwetting wall It also considers situation both reced...
