Overview on Oscillating Water Column Devices

Materials Research Proceedings, 2022
Abstract. Oscillating-water-column (OWC) converters, of fixed structure or floating, are an important class of wave energy devices. A large part of wave energy converter prototypes deployed so far into the sea are of OWC type. The paper presents a review of recent advances in OWC technology, including sea-tested prototypes and plants, new concepts, air

Oscillating water column control and monitoring

OCEANS 2016 MTS/IEEE Monterey, 2016
This article covers research into cost reduction pathways for wave energy. The primary focus is the development and test of reliable and controllable power take-off (PTO) technology for oscillating water column converters (OWC). This is highly relevant to the ocean energy challenge.

Numerical investigation of offshore oscillating water column devices

Renewable Energy, 2022
The main objective of this paper is to analyse the hydrodynamic efficiency of offshore stationary OWC devices with different configurations through two-dimensional computational fluid dynamics simulations. The two-dimensional incompressible Reynolds-Averaged Navier-Stokes equations and the Shear Stress Transport (SST) k-ω turbulence model are solved ...

The Hydrodynamic Efficiency of an Oscillating Water Column

24th International Conference on Offshore Mechanics and Arctic Engineering: Volume 2, 2005
An oscillating water column device enables the conversion of wave energy into electrical energy via wave interaction with a semi-submerged chamber coupled with a turbine for power take off. This present work concentrates on the wave interaction with the semi-submerged chamber, whereby a shore based oscillating water column (OWC) is studied ...

Oscillations of a water column beneath trapped air

American Journal of Physics, 2011
We investigate the natural oscillations of a water column beneath air trapped in a tube and demonstrate that the frequency of oscillation is lowest when the tube is about half full of water, and is higher when the tube is either mostly full or mostly empty. The familiar concepts of hydrostatics, ideal gases, and damped harmonic motion are indispensible

Phase Control for the Oscillating Water Column

1986
In this paper we investigate the use of optimal control techniques for improving the efficiency of the power-conversion system in an oscillating water column device. A mathematical model of the system is developed and an optimal control strategy for power-generation is determined.

Modeling of Oscillating Water Column wave energy systems

2016 World Automation Congress (WAC), 2016
Within the different types of on-shore wave-based ocean energy devices, Oscillating Water Column (OWC) converters are one of the widely used ones. This work deals with the modeling and simulation of OWC on-shore wave power plants. The study is particularized for the case of the Mutriku's MOWC power plant.

Hydrodynamic characteristics of an oscillating water column device

Applied Ocean Research, 1995
We consider a wave energy device consisting of a thin vertical surface-piercing barrier next to a vertical wall in finite depth water. Power is extracted due to a normally incident wave forcing the free surface of the fluid between the barrier and the wall to oscillate, in turn pumping the volume of air above the free surface through a uni-directional ...
