Two-phase flows involving capillary barriers in heterogeneous porous media

We consider a simplified model of a two-phase flow through a heterogeneous porous medium, in which the convection is neglected. This leads to a nonlinear degenerate parabolic problem in a domain shared in an arbitrary finite number of homogeneous porous media. We introduce a new way to connect capillary pressures on the interfaces between the homogeneous domains, which leads to a general notion...

Microscale extraction and phase separation using a porous capillary.

We report the use of a porous polytetrafluoroethylene capillary for the inline separation of liquid-liquid segmented flows, based on the selective wetting and permeation of the porous capillary walls by one of the liquids. Insertion of a narrow flow restriction at the capillary outlet allows the back pressure to be tuned for multiple liquid-liquid combinations and flow conditions. In this way, ...

Experimental Study of Dynamic Capillary Pressure Effect in Two-phase Flow in Porous Media

There is strong evidence in the literature that traditional equations describing two-phase flow processes in porous media may be inadequate under non-equilibrium or dynamic conditions. There exist theories that propose that the capillary pressure depends not only on saturation but also on the time rate of change of saturation. In this work, the significance of dynamic effects in the capillary p...

Prediction of Time of Capillary Rise in Porous Media Using Artificial Neural Network (ANN)

An Artificial Neural Network (ANN) was used to analyse the capillary rise in porous media. Wetting experiments were performed with fifteen liquids and fifteen different powders. The liquids covered a wide range  of  surface  tension ( 15.45-71.99  mJ/m2 )  and  viscosity (0.25-21 mPa.s). The powders also provided an acceptable range of particle size (0.012-45 μm) and surface free...

The effect of capillary forces on immiscible two-phase flow in heterogeneous porous media

A selection of these reports is available in PostScript form at the Faculty's anonymous ftp-Abstract We consider the one-dimensional two-phase ow including capillary eeects through a heterogeneous porous medium. The heterogeneity is due to the spatial variation of the absolute permeability and the poros-ity. Both these quantities are assumed to be piecewise constant. At interfaces where the roc...
