Full title: "Prediction of the interaction between ocean waves and tidal turbine
arrays through machine learning"
Tidal-stream turbines operate in harsh environmental conditions, with ocean
waves likely leading to extreme conditions that can trigger large structural
loads or modulate the turbine’s wake dynamics. This project will adopt and
extend an in-house high-fidelity numerical simulation tool (DOFAS – Digital
Offshore FArms Simulator) to represent realistic ocean conditions for bottom-
fixed and floating tidal turbines. This numerical model is essential to
accurately quantifying the wave-current-turbine interaction, as they allow to
control the variation of the wave’s characteristics, turbine operating point and
environmental turbulent flow conditions. Understanding of all the former
conditions is critical to inform industry about the performance of tidal
turbines and to develop a machine learning model trained on flow and turbine
loading data from a set of flow conditions that would allow to extrapolate to
the any wave climate (wave height and period) to could be found at any tidal
site.
High-fidelity simulation data will be used to build the machine-learning model
to be then embedded into a GPU-accelerated blade-element momentum solver that
will be made open-source to enable direct impact with world-leading industry,
with whom the supervisory team has established collaborations for more than a
decade. This multi-fidelity model integration is ground-breaking.
The project has two main objectives:
O1: Generation of a comprehensive dataset from large-eddy simulations using
actuator line method which also needvalidation for laboratory- and full-scale
tidal-stream turbines.
O2: Inform a machine-learning using both LES and blade-element momentum code to
enable turbine loading calculations at unprecedented speed which will be
expanded for a wider range of wave conditions.
Eligibility
Candidates must have a 1st or high 2i in a degree, ideally at Masters level, in
an Engineering subject, Physics, Mathematics, or Atmospheric Sciences. Knowledge
in fluid mechanics, numerical methods and computational modelling is necessary.
The student is expected to have prior experience writing codes on Fortran or
C/C++, and experience on Linux systems. No previous experience with machine
learning is required, although it would be advantageous. The ideal candidate is
expected to have a strong interest in renewable energy, be enthusiastic about
physics-based computational modelling, be able to have a proactive attitude
towards problem solving independently, and ability to work in multidisciplinary
teams.
This project has to start between 1st July 2025 and 30th September 2025.
