The high variability and unpredictability of renewable energy resources require optimization the extraction, by operating at best efficiency point, which can be achieved through optimal control strategies. In particular, wave forecasting models valuable for strategies in converter devices. This work intends to exploit short-term potential on an oscillating water column equipped with innovative ...

The present study deals with the performance of an U-shaped oscillating water column device under action oblique incident waves. To solve associated boundary value problem, dual element method (DBEM) is used. Various physical parameters OWC device, such as radiation susceptance and conductance coefficients, hydrodynamic efficiency, are analyzed for a wide range wave structural parameters. revea...

This paper reports on an ongoing international effort to establish guidelines for numerical modeling of wave energy converters, initiated by the International Energy Agency Technology Collaboration Program Ocean Systems. Initial results point absorbers were presented in previous work, and here we present a breakwater-mounted Oscillating Water Column (OWC) device. The experimental model is at sc...

A cross-flow air turbine, which is a self-rectifying, air-driven was designed and proposed for the power take-off (PTO) system of an oscillating water column (OWC) wave energy converter (WEC). To predict complicated non-linear behavior turbine in OWC, numerical experimental investigations were accomplished. The geometries nozzle rotor optimized under steady-flow conditions, performance analysis...
