Dissipative Particle Dynamics and other particle methods for multiphase fluid flow in fractured and porous media
Paul Meakin, Zhijie Xu
Particle methods are less computationally efficient than grid based numerical solution of the Navier Stokes equation. However, they have important advantages including rigorous mas…
Two-phase flow simulations at 0-4 degrees inclination in an eccentric annulus
C. Friedemann, M. Mortensen, J. Nossen
Multiphase flow simulations were run in an eccentric annulus. The dimensions of the annulus were 0.1 and 0.05 m for the outer and inner cylinders, respectively, and the mixture vel…
Linear motion of multiple superposed viscous fluids
Magnus Vartdal, Andreas Nygård Osnes
In this paper the small-amplitude motion of multiple superposed viscous fluids is studied as a linearized initial-value problem. The analysis results in a closed set of equations f…
Upscaling of Solute Transport in Heterogeneous Media with Non-uniform Flow and Dispersion Fields
Zhijie Xu, Paul Meakin
An analytical and computational model for non-reactive solute transport in periodic heterogeneous media with arbitrary non-uniform flow and dispersion fields within the unit cell o…
