Abstract

This study investigates the improvement of Oscillating Water Column (OWC) performance by employing a parabolic shoal to converge wave energy towards the device. Numerical simulations were conducted across a range of wavelengths for circular and rectangular OWC geometries, evaluating key performance metrics.
