Langmuir-type vortices in boundary layers driven by a criss-cross wavy wall topography
Andreas H. Akselsen, Simen Å. Ellingsen
We investigate a mechanism to manipulate wall-bounded flows whereby wave-like undulations of the wall topography drives the creation of bespoke longitudinal vortices. A resonant in…
Sheared free-surface flow over three-dimensional obstructions of finite amplitude
Andreas H. Akselsen, Simen Å Ellingsen
When shallow water flows over uneven bathymetry, the water surface is modulated. This type of problem has been revisited numerous times since it was first studied by Lord Kelvin in…
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…
