A numerical approach for hydrodynamic performance evaluation of multi-degree-of-freedom floating oscillating water column (OWC) devices

open access: yesA numerical approach for hydrodynamic performance evaluation of multi-degree-of-freedom floating oscillating water column (OWC) devices
A numerical approach has been developed in this study for hydrodynamic analysis of complex-shaped oscillating water column (OWC) converters. Physically, in the circumstance when the device is free to move or moored in waves, the airflow movement inside the chamber is coupled tightly with the changing of the internal fluid surface and the hydrodynamic ...

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.

An integrated tool for modelling oscillating water column (OWC) wave energy converters (WEC) in vertical breakwaters

Journal of Hydro-Environment Research, 2018
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 ...

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.
