An Oscillating Water Column (OWC): The Wave Energy Converter
Journal of The Institution of Engineers (India): Series C, 2021Ocean 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

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.

Abstract This paper describes the preliminary developments of an innovative integrated tool for the numerical modelling of oscillating water column (OWC) wave energy converters (WEC) integrated in vertical breakwaters. The main purpose of the tool is the numerical modelling of wave propagation from offshore to nearshore, wave-structure interaction ...

This paper presents the performance analysis and improvement of electric power generation for Oscillating Water Colum (OWC) wave energy converter using Finite Element Analysis (FEA). The existing power take-off system in OWC is based on induction machines which not only suffer from poor efficiency but require significant maintenance also.

Energy Conversion and Management
Majority of wave energy converters (WEC) have a relatively narrower capture due to their design philosophy, which focus on matching WEC’s natural frequency to a single peak frequency of a seastate spectrum. This paper introduces an innovative “Pan Flute”-type WEC embedded into a breakwater.

An oscillating water-air column (OWC) is one of the most technically viable options for converting wave energy into useful electric power. The OWC system uses the wave energy to “push or pull” air through an air turbine, as illustrated simply in Fig. 1.
