Following the previous successful simulation of the Supergen ORE benchmark tidal turbine in steady currents, this project aims at moving the simulation to include unsteady flows with waves. An international collaboration is proposed for skills development and knowledge exchange by working with my research partners (Prof. Pinon, Dr Zilic de Arcos) at LOMC Université Le Havre Normandie, who have developed sophisticated wave modelling techniques for turbine simulations. The objective of the project will be to enable me to develop and port the wave modelling capabilities into the Oxford simulation tools. Such development is aligned with and will be beneficial to the next phase of the Supegen ORE tidal turbine benchmark project, aiming at model validation on experiments with artificially generated waves, as well as the EPSRC project CoTide, focusing on the co-design of tidal energy devices at commercial scales. The research activities will be facilitated via academic visits toLOMC with reciprocal visits. Research outcomes are expected to be published through conference and shared with industrial partners of Supergen ORE and CoTide.
