An Oscillating Water Column (OWC): The Wave Energy Converter

Journal of the Institution of Engineers (India): Series C, 2021
Ocean waves are a valuable resource of renewable energy that can make a significant contribution to the supply of electricity to countries situated offshore when used in great measure. An extensive range of innovations was proposed, investigated, and assessed in some cases under actual ocean conditions. OWC devices are an important class of wave energy

Numerical simulation of a heave-only floating OWC (oscillating water column) device

Energy, 2014
Abstract This paper reports on the development of a two-dimensional, fully nonlinear CFD (Computational Fluid Dynamics) model with dynamic mesh to analyze the performance of a heave-only floating OWC (oscillating water column) device. The model was validated against previous experimental, analytical and numerical results on wave–air–structure ...

An axial turbine in an innovative oscillating water column (OWC) device for sea-wave energy conversion

Ocean Engineering, 2018
Abstract Wells turbines, self-rectifying air-driven axial turbines, are typically used to convert pneumatic power available in the periodic reversed airflow in Oscillating Water Column (OWC) device into mechanical energy. However, such turbines suffer from low aerodynamic efficiency; low powers produced, and narrow operating range.

Non-dimensional analysis for matching an impulse turbine to an OWC (oscillating water column) with an optimum energy transfer

Energy, 2015
Abstract OWC (Oscillating water column) wave power plants are widely used in ocean wave energy conversion. It is universally accepted that for a good efficiency of the plant, the turbine and the chamber should match each other according to the wave climate site.

Performance analysis of sea wave power plant oscillating water column system (SWPP-OWC)

AIP Conference Proceedings, 2022
One of the technological devices that can be used to generate electricity from ocean waves is the Oscillating Water Column (OWC) system. This system utilizes the rising and falling motion of the water in the air column to turn turbines and generate electricity.
