Liquid water transport inside the gas diffusion layers (GDLs) plays a vital role in management of proton exchange membrane fuel cells (PEMFCs). In this study, an improved pseudopotential multiphase lattice Boltzmann model is firstly developed to realize actual density and viscosity ratios porous media. The proposed based on non-orthogonal multiple-relaxation-time (MRT) LB new wettability bounda...

The wetting of a surface by liquid is crucial part many natural and industrial processes. Despite numerous existing studies, some elements wetting-drying such as contact angle variation during flow, are still poorly understood, yet it piece information needed for modeling fluid displacements in capillary-dominated flows. In the context multi-phase flow porous media, scarcity direct measurements...

Abstract Nowadays, as the oil reservoirs reaching their half-life, using enhanced recovery methods is more necessary and common. Simulations are synthetic process of real systems. In this study, simulation water surfactant injection into a porous media containing (two-phase) was performed computational fluid dynamics method on image micro-model. Also, selected anionic sodium dodecyl sulfate, wh...

Capillary pressure (Pc) curves acquired using the Magnetic Resonance Imaging (MRI) technique, call GIT-CAP, have 70-100 data points. This extra data, when compared with traditional porous plate or centrifuge techniques, allows for the interpretation of more information from the Pc curve. In particular, the pore throat size and relative permeability can be extracted. The pore throat size can be ...

In this paper we consider the process of one-dimensional redistribution of two immiscible and incompressible uids in a heterogeneous porous medium. We treat in detail the special case in which the initial saturation as well as the properties of the porous medium have a single coinciding discontinuity. Then the time-dependent saturation proole is of self-similar form, i.e. depends only on x= p t...

We present a pore-scale network model of twoand three-phase flow in disordered porous media. The model reads three-dimensional pore networks representing the pore space in different porous materials. It simulates wide range of twoand three-phase pore-scale displacements in porous media with mixed-wet wettability. The networks are composed of pores and throats with circular and angular cross sec...

The constitutive relation that describes the amount of nonwetting ̄uid phase entrapment is critical to the modeling of multiphase ̄ow in porous media, but it has received insucient attention in the literature. We studied this relation using both experimental and modeling approaches: we used a nondestructive, X-ray monitored, long-column experiment that yielded a rich data set for two di€erent p...

In oil reservoirs, if mainly has wettability in the solid phase, such as carbonate medium is oil-wetted. For oil-wetted porous media containing an and water two-phase flow, there are electric double layers at both oil–solid interface oil–water interface, which can stimulate seismoelectric effect. To date, most of studies on effects have focused water-wetted media, however, few reported cases es...

Complexities in pore scale structure, rock-fluid and fluid-fluid interactions have a profound effect on the estimation of reserves, reservoir recovery and productivity in reservoir core material. These complexities determine the pore scale distribution of fluids within the pore space, which, in turn, determine the petrophysical response of the rock. A very important example is the estimation of...

We use the model described in Piri and Blunt [Phys. Rev. E 71, 026301 (2005)] to predict two- and three-phase relative permeabilities of Berea sandstone using a random network to represent the pore space. We predict measured relative permeabilities for two-phase flow in a water-wet system. We then successfully predict the steady-state oil, water, and gas three-phase relative permeabilities meas...
