The 'Oscillating Wave Surge Converter' (OWSC) is a hybrid between the Japanese 'Pendulor' system and the LIMPET shoreline OWC. The device has one or more vanes like a segment of a water wheel with its axle spanning a recess in the shoreline or a caisson in the nearshore zone. It responds to the predominant horizontal fluid motion in shallow and intermediate depth waves and its response is strongly influenced by a variable cross section water column trapped between the vanes and an inclined back plane. The work programme involves model testing in 2D and 3D wave-tanks and numerical modelling using the AMAZON suite of programs developed at MMU. They will enable the parameter space to be extensively mapped and heuristic relationships for wave energy converters in shallow water developed. The physical models enable calibration of the numerical models, which is most easily done using PIV. They also ensure that the numerical models maintain sufficient accuracy in the cases investigated. The 2D models enable particular parameters, such as the effect of the inclined back plane to be isolated and studied in detail. The 3D models relate to a more realistic scenario and can provide device productivity results. The primary deliverable will be design guidance for OWSC's. The OWSC has potential in its own right, but could also be used to test power take-off systems for offshore devices. In addition, the developments in numerical modelling of shallow water hydrodynamics will have application to other types of coastal structure._2.
