3D NUMERICAL ANALYSIS ABOUT THE SHAPE INFLUENCE OF THE HYDRO-PNEUMATIC CHAMBER IN AN OSCILLATING WATER COLUMN (OWC) [PDF]

Revista de Engenharia Térmica, 2015
The oceans represent one of the major energy natural resources, which potentially can be used to supply the World energy demand. In the last decades some devices to convert the wave ocean energy into electrical energy have been studied. In this work the operating principle of an Oscillating Water Column (OWC) converter was analyzed with a transient 3D ...
