Aggregation in Charged Nano Suspensions
J. H. Werth, S. M. Dammer, H. A. Knudsen +2
In order to control aggregation phenomena in suspensions of nanoparticles, one often charges the particles electrically, e.g. by triboelectric charging. Stabilization of suspension…
Agglomeration of Oppositely Charged Particles in Nonpolar Liquids
Jochen H. Werth, Henning Knudsen, Haye Hinrichsen
We study the aggregation of insulating electrically charged spheres suspended in a nonpolar liquid. Regarding the van der Waals interaction as an irreversible sticking force, we ar…
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…
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…
A new relation between pressure and fractional flow in two-phase flow in porous media
Henning Arendt Knudsen, Alex Hansen
We study average flow properties in porous media using a two-dimensional network simulator. It models the dynamics of two-phase immiscible bulk flow where film flow can be neglecte…
Bulk Flow Regimes and Fractional Flow in 2D Porous Media by Numerical Simulations
Henning Arendt Knudsen, Eyvind Aker, Alex Hansen
We investigate a two-dimensional network simulator that model the dynamics of two-phase immiscible bulk flow where film flow can be neglected. We present a method for simulating th…
