Cluster evolution in steady-state two-phase flow in porous media
Thomas Ramstad, Alex Hansen
We report numerical studies of the cluster development of two-phase flow in a steady-state environment of porous media. This is done by including biperiodic boundary conditions in…
Self-Affinity in the Gradient Percolation Problem
Alex Hansen, G. George Batrouni, Thomas Ramstad +1
We study the scaling properties of the solid-on-solid front of the infinite cluster in two-dimensional gradient percolation. We show that such an object is self affine with a Hurst…
Fracture Roughness and Correlation Length in the Central Force Model
Jan Øystein Haavig Bakke, Thomas Ramstad, Alex Hansen
We measure the roughness exponent and the correlation length exponent of a stress-weighted percolation process in the central force model in 2D. The roughness exponent is found to…
