Abstract

The oscillating-water-column (OWC) is a ubiquitous style of wave-energy-converter for harnessing significant power from ocean waves. A new configuration of OWC described here as a vented-OWC provides opportunity to simplify air-turbine design by limiting the power extraction to inhalation mode. The asymmetric airflow profile of the vented-OWC requires a unidirectional-turbine configuration to be adopted.
