Personal profile
Research interests
My research addresses fundamental and applied engineering problems aimed at maximising societal value of offshore renewable energy (ORE) technologies. The primary focus is on development and validation of predictive models for unsteady flow-structure-interaction problems with particular interest in the physical processes defining wakes in turbulent flow, unsteady loading, response and energy supply from arrays of tidal- and wind turbines, and interactions between large offshore renewable energy farms. Research involves numerical modelling, physical experiments, field data campaigns and collaboration with multiple disciplines, environmental scientists, and economists.
Opportunities
Postgraduate research projects available or considered on topics related to:
- turbulent channel flows and wave mechanics,
- tidal stream system design and modelling,
- offshore wind farm flows,
- flow-structure-interaction problems related to offshore infrastructure response and loading.
Projects may draw upon a range of methods such as experimental studies of hydrodynamics and / or numerical modelling of differing fidelities.
Links to supervised research projects and the resultant PhD Theses are available under "Supervised Work" (see tab at top of this page).
