Title: Optimization of the geometry of axisymmetric point-absorber wave energy converters

Abstract: Wave energy represents an abundant source of renewable energy, but as yet the potential is not fully utilized. Aiming to exploit this vast potential, many theoretical, experimental and pilot-scale studies have been conducted on wave energy converters (WECs), however as yet there has been no convergence on the optimal shape of a WEC. Furthermore, there is no agreed-upon definition of what it means for a WEC to be `optimal’ and no established framework to find optimal shapes. In this talk, I will present a novel, scientifically rigorous framework to find practically realistic optimal shapes of WECs. I will show a few elements of the procedure which allow for a general and efficient optimization, as well as some example results from the optimization and original insights into what makes shapes optimal for wave energy extraction. Finally, I will present a generalization of the optimal geometry to irregular sea states. The methodology developed, along with the results found, in this work will help to inform future WEC development. Through the discovery of WEC shapes which extract maximum power and require minimum material use, whilst ensuring the WEC shapes are practically feasible, this thesis is a step forward in our understanding of WECs and ultimately contributes towards wave energy becoming a viable source of renewable energy in future.
