A statistical mechanics framework for immiscible and incompressible two-phase flow in porous media

Alex Hansen et al.

Summary: We have developed a statistical mechanics model based on the Jaynes maximum entropy principle to describe immiscible and incompressible two-phase flow in porous media under local steady-state conditions. A cluster entropy is used to capture our lack of knowledge about the fluid and flow configurations in the pore space. This approach introduces two new variables, agiture and flow derivative, which correspond to the level of agitation of the fluids and the saturation, respectively. By applying a thermodynamics-like formalism, we uncover previously unknown relationships and fluctuations between these flow variables. This formalism offers new approaches to characterize porous media and multi-phase flow for practical applications, while maintaining a manageable number of variables.

The Co-Moving Velocity in Immiscible Two-Phase Flow in Porous Media

Subhadeep Roy et al.

Summary: This study presents a continuum approach to describe immiscible two-phase flow in porous media, by transforming the relationship between two velocity couples and incorporating the constitutive equation directly. The results show that this method can provide consistent and effective constitutive equations under different parameters.

Relative permeability as a stationary process: Energy fluctuations in immiscible displacement

James E. McClure et al.

Summary: Relative permeability is derived from conservation of energy and used to model fluid flow through porous materials. The study finds dynamic connectivity and explores the distribution of energy fluctuations during steady-state flow. It demonstrates the effectiveness of the conventional relative permeability relationship in simulating energy dissipation in systems with complex pore-scale dynamics.

Rheology of Immiscible Two-phase Flow in Mixed Wet Porous Media: Dynamic Pore Network Model and Capillary Fiber Bundle Model Results

Hursanay Fyhn et al.

Summary: The study investigated immiscible two-phase flow in porous media with mixed wet conditions using a capillary fiber bundle model and a dynamic pore network model. The results showed that mixed wettability significantly influences the rheology in terms of the dependence of global volumetric flow rate on global pressure drop.
