A conformally mapped numerical wave tank supporting piston and flap wavemakers
Andreas Holm Akselsen
This paper advances the development of the conformally mapped model for accurate simulation of two-dimensional water waves, here with emphasis on mapping boundaries that represent…
Second-order theory for multi-hinged directional wavemakers
Andreas H. Akselsen
The second-order directional wavemaker theory for regular and irregular waves is extended to multi-hinged wavemakers and combined piston--flap wavemaker systems. Derived expression…
A precise conformally mapped method for water waves in complex transient environments
Andreas H. Akselsen
A two-dimensional water wave model based on conformal mapping is presented. The model is exact in the sense that it does not rely on truncated series expansions, nor suffer any num…
Designing vortices in pipe flow with topography-driven Langmuir circulation
Simen Å. Ellingsen, Andreas H. Akselsen, Leon Chan
We present direct numerical simulation of a mechanism for creating longitudinal vortices in pipe flow, compared with a simple model theory. By furnishing the pipe wall with a patte…
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…
