Modelling and control of a floating oscillating water column
… model of a Bent Backwards Duct Buoy (BBDB) Oscillating Water Column (OWC) Wave Energy Converter was created based on existing isolated numerical models of the different energy conversion systems utilised by an OWC. The novel aspect of this numerical model is that it incorporates the …

Power extraction from an oscillating water column along a coast
… coast. We study here the specific case where an Oscillating Water Column (OWC) is attached to the tip of a long breakwater. A three-dimensional numerical model of a skeletal geometry of the the Foz do Douro breakwater is developed in order to determine the response inside the OWC pneumatic …

Experimental and Numerical Modelling of a Multiple Oscillating Water Column Structure
… both wave and wind energy, using an array of oscillating water columns (OWC) and conventional wind energy technology. The focus of this thesis is on the wave energy-capturing aspects of the proposed platform. A 1:50, physical scale model of the proposed platform is described, and a tank …

Performance and power smoothing of innovative closed-circuit oscillating water column wave energy converter
… needed to produce affordable electrical energy. Oscillating-Water-Column (OWC) devices are among the most promising types of wave energy converters because of their relative simplicity. The present work investigates the possibility of improving the performance of this well-established concept by …

Synergistic design of a combined floating wind turbine - wave energy converter
… being said, this thesis considers heave-mode oscillating water column WEC's that are linked to the FWT platform by 4-bar linkages, so that the FWT and WEC's are uncoupled for small heave motions and rigidly coupled in all other degrees of freedom. It is shown that this configuration allows the …

Theoretical modelling of two wave-power devices
… thesis we focus on two specific devices: the Oscillating Water Column (OWC), and the buoys. In the first part of this thesis we examine the effects of coastline geometry on the performance of an OWC. Under the assumption of inviscid irrotationnal flow, we develop a linear theory for the …

Implementation and Demonstration of a Time Domain Modeling Tool for Floating Oscillating Water Columns
… Converters (WECs). One such WEC is the floating Oscillating Water Column (OWC), which has been successfully field tested and warrants further exploration. This research implements a publicly accessible code in MatLab and SimuLink to simulate the dynamics of a floating OWC in the time domain. This …

Performance and hull pressure analysis of scaled physical testing of a wave energy converter
… possible degree before being put into an open-water operational environment. This study describes a physical tank testing campaign of one such model, the Ocean Energy (OE) Buoy, a floating oscillating water column wave energy converter. The walls of the OE Buoy are open to allow water to freely …

Wave impacts on rectangular structures
… wave climate unknown, but the aeration of the water will also be subject to uncertainty. This affects rather dramatically the speed of sound in the water/bubble mixture and hence the value of the acoustic pressure that acts as a maximum cutoff for pressure calculated by any incompressible …
