Nearshore oscillating wave surge converters and the development of Oyster.
Oscillating wave surge converters (OWSCs) are a class of wave power technology that exploits the enhanced horizontal fluid particle movement of waves in the nearshore coastal zone with water depths of 10-20 m. OWSCs predominantly oscillate horizontally in surge as opposed to the majority of wave devices, which oscillate vertically in heave and usually are deployed in deeper water. The character...
متن کاملInteractions Between an Oscillating Wave Surge Converter and a Heaving Wave Energy Converter
In this paper, we investigate the mutual hydrodynamic interactions between two different kinds of devices, namely, an Oscillating Wave Surge Converter modeled as an oscillating flap and a generic Heaving Wave Energy Converter modeled as a vertical truncated cylinder. A three-dimensional mathematical model based on linear potential flow theory is developed. It is assumed that the effects of the ...
متن کاملHeaving buoys, point absorbers and arrays.
Absorption of wave energy may be considered as a phenomenon of interference between incident and radiated waves generated by an oscillating object; a wave-energy converter (WEC) that displaces water. If a WEC is very small in comparison with one wavelength, it is classified as a point absorber (PA); otherwise, as a 'quasi-point absorber'. The latter may be a dipole-mode radiator, for instance a...
متن کاملAnalytical and computational modelling for wave energy systems: the example of oscillating wave surge converters
The development of new wave energy converters has shed light on a number of unanswered questions in fluid mechanics, but has also identified a number of new issues of importance for their future deployment. The main concerns relevant to the practical use of wave energy converters are sustainability, survivability, and maintainability. Of course, it is also necessary to maximize the capture per ...
