Oscillating water columns (OWCs) are a type of wave energy converter [1] that harness energy from the oscillation of the seawater inside a chamber or hollow caused by the action of waves. OWCs have shown promise as a renewable energy source with low environmental impact.

2023年6月15日 · The study aims to demonstrate that, unlike traditional land-based OWC systems, the width, length, and height of the neck of a Helmholtz resonator-based OWC device can improve the harvesting of wave energy.

2016年1月1日 · Oscillating-water-columns (OWCs) are a major class of wave energy converters. Only moving part of OWC is air turbine rotor directly driving electrical generator. OWCs may be bottom-standing, breakwater-integrated and floating. More efficient new-generation air turbines enhance OWC power performance.

2024年10月29日 · The present study investigates the hydrodynamic performance of an onshore oscillating water column (OWC) device placed over an undulated bottom topography by analyzing its hydrodynamic efficiency under the action of combined wave–current interaction.

2022年12月1日 · OWC devices present several advantages over other WECs, particularly the minimal number of moving parts in a typical OWC PTO system: an air turbine and a standard generator, in the simplest configurations. Furthermore, these components are located above the water surface, therefore improving device reliability and simplifying maintenance.

2025年1月18日 · Hybrid wind–wave energy devices have attracted significant attention for their potential to efficiently harness marine energy while reducing construction costs. In this work, the hydrodynamic performance of an oscillating water column (OWC) device installed in an offshore wind turbine was investigated.

2021年7月9日 · OWC devices are an important class of wave energy method. The majority of designs used in the conversion of wave energy into the sea are OWC. There is a fixed or floating hollow structure in an OWC under the water surface, which pits the air over the inner free zone.

2016年1月1日 · Oscillating-water-column (OWC) devices, of fixed structure or floating, are an important class of wave energy devices. A large part of wave energy converter...

2025年3月19日 · The experimental study of oscillating water column (OWC)-type wave energy converters (WECs) usually focuses on the performance of a WEC in regular wave conditions, as a function of available ...

2024年12月7日 · The energy present in the ocean surface waves can be extracted using an oscillating water column (OWC) device. In the present work, the performance characteristics of a normal OWC, an opposite OWC ...
