Charlotte (North Carolina), ISSN 0749-0208. Wave energy offers a promising renewable energy source with added benefits for coastal protection. This study investigates the hydrodynamic performance of a fixed Oscillating Water Column (OWC) Wave Energy Converter (WEC) under different wave conditions, focusing on wave period, wave height, and device draft. The obtained results show that peak hydrodynamic efficiency occurs at the natural frequency of the water column and decreases with increased draft due to reduced water mass in the OWC chamber. This highlights the need for thorough evaluation of site-specific wave conditions for optimal power extraction. These findings are crucial for the geometry optimization and site selection of fixed OWC devices, contributing to the advancement of wave energy conversion technology and sustainable energy solutions.
