Abstract
This paper investigates the modelling of a quarter scale offshore oscillating water column (OWC) wave energy converter (WEC) with results from a prototype device used to validate the model. The OWC WEC utilises a specialised bi-directional air turbine known as the Wells turbine. The paper investigates the modelling of this turbine and studies the electrical output from a generator to be coupled to the turbine. Simulations of the proposed system are carried out under multiple sea state conditions and are compared to results from the prototype device located at an experimental test site in Ireland.
