Eagre/Aegir: high-seas wave-impact modelling

European Union European Industrial Doctorates 2020-2023 (project 859983)

Extreme Waves & Wave Impact on Windturbines

The Maritime Research Institute Netherlands MARIN is a world-leading institute for hydrodynamic research and maritime technology (video).
The overall objective of the Eagre project is to create and deliver computational/mathematical modelling tools for solving problems in maritime engineering, based on advanced mathematical/numerical analysis and efficient implementation and testing in a general finite-element simulation environment offered by Firedrake (Imperial College with Leeds). Our key task is to offer training/ research such that a so-called "numerical wavetank" is established by two Early Stage Researchers (ESRs) for use in maritime-engineering wave basins, such as operational for consulting at the Maritime Research Institute Netherlands (MARIN Academy). Our research will provide the ESRs with a skill set that is highly attractive in the job market to employers engaged in high-end consulting.
The integrated objectives are to create:
(i) a numerical wavetank “ExtremeWaves” (ESR1) concerning modelling of extreme or rogue waves in wave basins integrated with
(ii) a numerical wavetank “WaveTurbineImpact” (ERS2) concerning wave-structure interactions, especially wave-impact, on a dynamic wind-turbine mast.
The overall objectives build on our recent and current collaborative work (between U. of Leeds and MARIN Academy) on the modelling of water waves and wave-structure interactions with (dis)continuous Galerkin finite-element methods. The above objectives offer challenging demands, not least because the prediction of wave motion around moving or flexible structures is a difficult computational task as a result of the requirement to track (generally using a sophisticated approximation) the a-priori-unknown nonlinear air-water and water-structure interfaces (and their cross-section, the waterline). Conquering these demands is timely because numerical simulations are cheaper than laboratory tests. Moreover, because in realistically motivated challenges mathematical modelling, laboratory testing and cross-validation via computational simulation are inextricably entwined, we view them all as essential components in our so-called "Research Trinity".

Eagre/Aegir: "a high wave (often dangerous) caused by tidal flow (as by colliding tidal currents or in a narrow estuary)". The Treat Aegir is well-known tidal bore on the River Trent, relatively close to Leeds. Eagre is part of the Leeds Institute for Fluid Dynamics.
