Performance Analysis of a 3D Axisymmetric Oscillating Water Column

Energy Procedia, 2014
AbstractThis paper presents an analysis, by numerical simulation, of the effects of some geometric parameters on the efficiency of an axisymmetric oscillating water column wave energy converter by using ANSYS ICEM CFD and CFX. The study is focused, principally, on the variation of power take off size, front wall shape, air column size, wave conditions ...
