Experimental Study on the Aerodynamic Performance and Wave Energy Capture Efficiency of Square and Curved OWC Wave Energy Conversion Devices

To develop novel wave energy conversion devices (WECDs) with excellent performance, the relative height and pressure in chambers of square curved oscillating water column (OWC) WECDs were compared through physical model tests, effects regular incident factors, opening length, width, chamber volume on aerodynamic performance capture efficiency (WECE) investigated. The results indicated good for both OWC WECDs. As increased, surface elevation, WECE, all while decreased. When area WECD increased. increased decreasing volume; however, intrachamber WECE decreased increasing volume. It is recommended that, actual engineering applications, overall device be improved by air chamber.
