Two-phase flow in porous media: dynamical phase transition
Henning Arendt Knudsen, Alex Hansen
Two-phase flow systems in porous media have complex dynamics. It is well established that a wide range of system parameters like viscosities and porosity as well as flow parameters…
Roughness of Interfacial Crack Front: Correlated Percolation in the Damage Zone
Jean Schmittbuhl, Alex Hansen, G. George Batrouni
We show that the roughness exponent zeta of an in-plane crack front slowly propagating along a heterogeneous interface embeded in a elastic body, is in full agreement with a correl…
Origin of the Universal Roughness Exponent of Brittle Fracture Surfaces: Correlated Percolation in the Damage Zone
Alex Hansen, Jean Schmittbuhl
We suggest that the observed large-scale universal roughness of brittle fracture surfaces is due to the fracture process being a correlated percolation process in a self-generated…
Generic differential equation for fractional flow of steady two-phase flow in porous media
Henning Arendt Knudsen, Alex Hansen
We report on generic relations between fractional flow and pressure in steady two-phase flow in porous media. The main result is a differential equation for fractional flow as a fu…
Heterogeneous Interfacial Failure between Two Elastic Blocks
G. George Batrouni, Alex Hansen, Jean Schmittbuhl
We investigate numerically the failure process when two elastic media, one hard and one soft that have been glued together thus forming a common interface, are pulled apart. We pre…
Specific Heat upon Aqueous Unfolding of the Protein Interior: A Theoretical Approach
Audun Bakk, Johan S. Hoye, Alex Hansen
We study theoretically the thermodynamics, over a broad temperature range (5 C to 125 C), related to hydrated water upon protein unfolding. The hydration effect is modeled as inter…
