Pressure drop-flow rate nonlinearity in bubble trains through a capillary bundle
Paolo Botticini, Davide Picchi, Santanu Sinha +1
We investigate the effective rheology of a train of elongated bubbles of negligible viscosity flowing in capillary tubes. Building upon the classical Bretherton theory for a single…
Immiscible two-phase flow in porous media: a statistical mechanics approach
Alex Hansen, Santanu Sinha
The central problem in the physics of immiscible two-phase flow in porous media is to find a proper description of the flow at scales large enough so that the medium may be regarde…
Coordination-number dependent universality in Mixed Wet Percolation
Jnana Ranjan Das, Santanu Sinha, Alex Hansen +1
Mixed-wet percolation was introduced recently in the context of two-phase flow in porous media. In this model, the sites of the primal lattice are occupied with a certain probabili…
Glassy phase transition in immiscible steady-state two-phase flow in porous media
Santanu Sinha, Humberto Carmona, José S. Andrade +1
Two-phase flow in porous media is a ubiquitous phenomenon that has been studied for well over a century. However, we still lack a successful theory that predicts flow on a macrosco…
Mixed-wet percolation on a dual square lattice
Jnana Ranjan Das, Santanu Sinha, Alex Hansen +1
We present a percolation model that is inspired by recent works on immiscible two-phase flow in a mixed-wet porous medium made of a mixture of grains with two different wettability…
Thermodynamics-Like Formalism for Immiscible and Incompressible Two-Phase Flow in Porous Media
Alex Hansen, Santanu Sinha
It is possible to formulate immiscible and incompressible two-phase flow in porous media in a mathematical framework resembling thermodynamics based on the Jaynes generalization of…
