Hydrodynamic Investigation of a Concentric Cylindrical OWC Wave Energy Converter

Energies, 2018
A fixed, concentric, cylindrical oscillating water column (OWC) wave energy converter (WEC) is proposed for shallow offshore sites. Compared with the existing shoreline OWC device, this wave energy device is not restricted by the wave directions and ...

CFD analysis of devices i oscillating water column - OWC

, 2015
The paper is about the development of a fluid-dynamic model for simulating the behaviour of a device for the production of electric energy based on an oscillating water column (OWC). First of all it has been developed a 3-D model of the device using a tool in order to create the grid used for the simulation.

Modelling Approaches of a Closed-Circuit OWC Wave Energy Converter

Journal of Marine Science and Engineering, 2019
The Tupperwave device is a wave energy converter based on the Oscillating Water Column (OWC) concept. Unlike conventional OWC devices, which are opened to the atmosphere, the Tupperwave device works in closed-circuit and uses non-return valves and ...
