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…

Geometric structure of parameter space in immiscible two-phase flow in porous media
Håkon Pedersen, Alex Hansen
In a recent paper, a continuum theory of immiscible and incompressible two-phase flow in porous media based on generalized thermodynamic principles was formulated (Transport in Por…

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…
