Heaving 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...

Heaving Point Internal Mass

A design study has been made of a wave energy converter in the form of a heaving buoy reacting against an internal moving mass. Phase control has been obtained by modulating the stiffness of the spring governing the moving mass. Promising results, agreeing closely with linear theory, have been obtained with two shapes of buoy. Mean annual captures of the order of 2OOW/tonne in a typical South U...

Quantitative Photo-Acoustic Imaging of Small Absorbers∗

In photo-acoustic imaging, energy absorption causes thermo-elastic expansion of optical absorbers, which in turn leads to propagation of a pressure wave. Recently, we have developed an efficient method for locating small absorbing regions inside a bounded domain from boundary measurements of the induced pressure wave and reconstructing the absorbed density. However, it is the absorption coeffic...

System Identification of a Heaving Point Absorber: Design of Experiment and Device Modeling

Abstract: Empirically based modeling is an essential aspect of design for a wave energy converter. Empirically based models are used in structural, mechanical and control design processes, as well as for performance prediction. Both the design of experiments and methods used in system identification have a strong impact on the quality of the resulting model. This study considers the system iden...

Experimental investigation of power capture from pitching point absorbers

This paper presents results from an experimental study on the power capture of bottom-pivoted pitching point absorbers in intermediate water depth subjected to regular and irregular waves. The present research investigates the respective influence of parameters such as geometry, damping and inertia modification (ballasting) on the performance of bottom-pivoted pitching wave energy converters in...
