A Numerical and Experimental Study on Performance Evaluation of Oscillating Water Column Wave Energy Converter

Abstract

In the present study, numerical analysis using CFD and experimental tests using the 2D wave flume were conducted to evaluate the primary energy conversion performance of the oscillating water columne waver energy converter (OWC WEC). In order to figure out the feasiblity of the dual power take-off (PTO) device, the efficiency of the primary energy conversion for the OWC chamber was studied with considering the single PTO or the dual PTO, in both of the numerical simulation and the experiment test. The improvement effect by the adoption of the dual PTO was discussed.
