چکیده
Although oscillating water column (OWC) wave energy converters are arguably one of the most studied technologies, it is not clear which chamber geometry, among all available alternatives, would provide best performance at a site interest. In this work, numerical model based on Navier-Stokes equations for two compressible fluids, using volume-of-fluid interface-capturing approach, implemented to determine performing OWC geometry in case study off Port Vigo (NW Spain). Four general shapes analyzed: classic, stepped-bottom, U-shaped and L-shaped, geometrical variants investigated. total, 18 geometries studied, considering same turbine them. It was found that L-shaped designs easily tuned resonate period Of these two, performs better. The achieved an design with shallow entrance, high horizontal duct wide vertical duct, maximum capture-width ratio 71.6% achieved.

On the Effects of Geometry Control on the Performance of Overtopping Wave Energy Converters
Overtopping wave energy converters (OWECs) are designed to extract energy from ocean waves based on wave overtopping into a reservoir, which is emptied into the ocean through a set of low-head turbines, and typically feature a low crest freeboard and a smooth impermeable steep slope. In the process of optimizing the performance of OWECs, the question arises whether adapting the slope geometry t...
متن کاملDesign optimization of hydraulic energy storage and conversion system for wave energy converters
Wave energy collected by the power take-off system of a Wave Energy Converter (WEC) is highly fluctuating due to the wave characteristics. Therefore, an energy storage system is generally needed to absorb the energy fluctuation to provide a smooth electrical energy generation. This paper focuses on the design optimization of a Hydraulic Energy Storage and Conversion (HESC) system for WECs. The ...
