A Study on Effects of Breakwater on Performance of OWC

Abstract

This study presents results of numerical simulations on the effects of the presence of breakwaters on the OWC (Oscillating Water Column) performance. CFD (Computational Fluid Dynamics) simulations using a commercial code, Star-CCM+, are done for evaluating performances of the OWC without and with considering the breakwaters in regular waves. Flow fields of the OWC in regular waves are shown as continuous contours, and the effects of the breakwater on the performance of OWC are evaluated. Finally, the cause of the performance improvement and reduction of OWC due to breakwater is discussed.
