Immiscible two-phase flow in porous media: Effective rheology in the continuum limit
Subhadeep Roy, Santanu Sinha, Alex Hansen
It is becoming increasingly clear that there is a regime in immiscible two-phase flow in porous media where the flow rate depends of the pressure drop as a power law with exponent…
Flow-Area Relations in Immiscible Two-Phase Flow in Porous Media
Subhadeep Roy, Santanu Sinha, Alex Hansen
We present a theoretical framework for immiscible incompressible two-phase flow in homogeneous porous media that connects the distribution of local fluid velocities to the average…
Creep failure in a threshold activated dynamics: Role of temperature during a sub-critical loading
Subhadeep Roy, Takahiro Hatano
Creep is a time-dependent deformation of solids at relatively low stresses, leading to the breakdown with time. Here we propose a simple model for creep failure of disordered solid…
Effective rheology of two-phase flow in a capillary fiber bundle model
Subhadeep Roy, Alex Hansen, Santanu Sinha
We investigate the effective rheology of two-phase flow in a bundle of parallel capillary tubes carrying two immiscible fluids under an external pressure drop. The diameter of each…
