Abstract

Three-dimensional cylindrical Oscillating Water Column (OWC) wave energy device is investigated in this work using both experimental and analytical methods. Non-linear Power take off system is simulated by an orifices-plate. Three different damping levels’ effects are studied. Results show that analytical method combining damping effect, taken from experiment, can provide a better prediction for the experiment. However, analytical method fails to include viscous effect. In addition, present results also suggests that in low wave frequency region, high damping leads to a better performance in capture factor as compared to a low damping case.
