Test results of a novel twin-rotor radial inflow self-rectifying air turbine for OWC wave energy converters
TL;DR: In this paper, a self-rectifying twin-rotor air turbine is used to equip an oscillating water column wave energy converter, which is based on a pair of conventional radial inflow rotors mounted on a common shaft, complemented by the corresponding inlet guide vane rows, by a curved-duct manifold arranged circumferentially in a periodic manner and by an axially moving cylindrical valve.

Investigation to Air Compressibility of Oscillating Water Column Wave Energy Converters
TL;DR: In this paper, the authors presented a study on air compressibility in OWC air chambers by theoretical analyses and relevant experimental studies, based on the first-order differential equation for the flowrate and the chamber pressure, which has been derived for the air flow under the assumptions of the isentropic process and known power take-off characteristics.

ANN-Based Airflow Control for an Oscillating Water Column Using Surface Elevation Measurements
TL;DR: This work aims to use the power of artificial neural networks (ANN) to recognize the different incoming waves in order to distinguish the strong waves that provoke the stalling behavior and generate a suitable airflow speed reference for the airflow control scheme.
