The Kelvin-Helmholtz/von Neumann Stability of Discrete Representations of the Two-Fluid Model for Stratified Two-Phase Flow
Andreas Holm Akselsen
Many dynamic pipe flow simulator tools are capable of predicting the onset of hydrodynamic flow instability through detailed simulation. These instabilities provide a natural mecha…
The Stability of Roll-Waves in Two-Phase Pipe Flow
Andreas Holm Akselsen
Roll-wave trains constitutes a well-known two-phase flow regime in pipes. There exists a one-parameter family of steady roll-wave train solutions, provided the flow conditions are…
Characteristic methods and Roe's method for the incompressible two-fluid model for stratified pipe flow
Andreas Holm Akselsen
This article examines the use of characteristic methods in stratified two-phase pipe flow simulations for obtaining non-dissipative flow predictions. A Roe scheme and several metho…
A Dual Grid Method for the Compressible Two-Fluid Model which Combines Robust Flux Splitting Methodology with High-Resolution Capturing of Incompressible Dynamics
Andreas Holm Akselsen
The speed of sound in two-phase pipe flow systems is often several orders of magnitude greater than the travelling speed of hydraulic information (volume fractions.) Dynamically si…
Weakly non-linear transient waves on a shear current: Ring waves and skewed Langmuir rolls
A. H. Akselsen, Simen Å. Ellingsen
We investigate the weakly nonlinear dynamics of transient gravity waves at infinite depth under the influence of a shear current varying linearly with depth. An analytical solution…
