Modelling the WITT wave energy converter

This presentation describes work undertaken as part of INNOVATE UK funding led by Witt Energy Ltd to investigate the efficacy of a novel design of wave energy converter (WEC). A sealed spherical hull is floating on the surface of the water (Fig. 2(b)) and is moored to the sea bed under a four point catenary mooring system. A mechanical device known as the WITT (Fig. 1) is housed within the hull...

Hydrodynamic modelling of a direct drive wave energy converter

In this article we present numerical studies of waves interacting with a cylindrical point absorber that is directly driving a seabed based linear generator. For waves useful for power conversion, the wave/point absorber interaction can be modelled, using potential theory assuming an inviscid irrotational incompressible fluid. The generator is modelled as a viscous damper. This paper pays speci...

Array Optimization for Tidal Energy Extraction in a Tidal Channel – a Numerical Modeling Analysis

This paper presents an application of a hydrodynamic model to simulate tidal energy extraction in a tidal dominated estuary in the Pacific Northwest coast. A series of numerical experiments were carried out to simulate tidal energy extraction with different turbine array configurations, including location, spacing and array size. Preliminary model results suggest that array optimization for tid...
