Aiming at achieving Net Zero emissions in the UK by 2050 and contributing to the reduction of carbon emissions globally in response to global warming, the Fluid Mechanics Research Group members work on a variety of research projects in the renewable energy sector, such as hydrodynamics of tidal turbines and its environmental impacts, survivability and hydrodynamics of wave energy converters, and stability and survivability of fixed and floating offshore wind turbines. The group also covers fundamental research relevant to the renewable energy sector, such as fluid-structure interaction and predictions of extreme marine environments.

Recent PhD Projects:

2023-present	Billy Colhoun	Multi-physics fully coupled model developments and assessments of floating offshore wind turbines
2019-present	Nijmeh Marouf	Hydrokinetic energy convertors: performance and environmental impact study
