… tidal resonance in the channel, a simple two dimensional model has been developed for a series of simulated estuaries, ranging from a simple box channel with a uniform flat bed to a simple wedge shaped channel with a solid barrier across, to a simulation of the Severn Estuary with topographic and bathymetric values. These modelsshow amplitudes and phases of elevation and current flow for each model scenario. model outputs show that overall tidal …

… effect that a mono-directional Power Take Off (PTO) has on the motions and power extraction of a Wave Energy Converter (WEC). A mono-directional damper is one where the resisting force only operates in one direction. The model comprises of a cylinder that is restrained to move in heave, reacting against an internal mass (also … mono-directional damper in parallel. This paper presents experimental results for a variety of different damping constants for mono-directional dampers which operate in both in expansion …

… The structural lifetime fatigue testing of tidal turbine blades is currently a challenge faced by the tidal industry. Due to the high stiffness and short length of composite tidal blades, it is not possible to perform resonant fatigue testing in the same way … too high a natural frequency which, if tested resonantly, would result in internal heating of the composite and lead to premature failure. The aerospace industry uses conventional …

… through proxies based on the device's size. When using an optimisation process capable of generating very diverse shapes, more complex objective functions may be required to ensure that resulting shapes truly minimise the levelised cost of energy. For this purpose, relevant cost factors with an effect on geometry, such as …

… A linear-generator topology is proposed for wave-energy applications. The main significance of the generator topology is that the relative position of the magnets, copper, and steels has been chosen so that there are no magnetic attraction forces between a stator and a permanent-magnet (PM) translator. The lack of magnetic forces and the modular nature of the generator topology make the manufacture and …
