Non-isothermal transport of multi-phase fluids in porous media. Constitutive equations
Signe Kjelstrup, Dick Bedeaux, Alex Hansen +2
We develop constitutive equations for multi-component, multi-phase, macro-scale flow in a porous medium exposed to temperature-, composition-, and pressure -gradients. The porous m…
Implications of Realistic Fracture Criteria on Crack Morphology
Bjørn Skjetne, Alex Hansen
We study the effects realistic fracture criteria have on crack morphology obtained in numerical simulations with a stochastic discrete element method. Results are obtained with two…
Non-isothermal transport of multi-phase fluids in porous media. The entropy production
Signe Kjelstrup, Dick Bedeaux, Alex Hansen +2
We derive the entropy production for transport of multi-phase fluids in a non-deformable, porous medium exposed to differences in pressure, temperature, and chemical potentials. Th…
A Renormalization Group Procedure for Fiber Bundle Models
Srutarshi Pradhan, Alex Hansen, Purusattam Ray
We introduce two versions of a renormalization group scheme for the equal load sharing fiber bundle model. The renormalization group is based on formulating the fiber bundle model…
Can Local Stress Enhancement Induce Stability in Fracture Processes? Part I: Apparent Stability
Jonas T. Kjellstadli, Eivind Bering, Martin Hendrick +2
By comparing the evolution of the local and equal load sharing fiber bundle models, we point out the paradoxical result that stresses seem to make the local load sharing model stab…
Mesoscopic Description of the Equal Load Sharing Fiber Bundle Model
Martin Hendrick, Srutarshi Pradhan, Alex Hansen
One aim of the equal load sharing fiber bundle model is to describe the critical behavior of failure events. One way of accomplishing this, is through a discrete recursive dynamics…
Stable and efficient time integration of a dynamic pore network model for two-phase flow in porous media
Magnus Aa. Gjennestad, Morten Vassvik, Signe Kjelstrup +1
We study three different time integration methods for a dynamic pore network model for immiscible two-phase flow in porous media. Considered are two explicit methods, the forward E…
