Efficiency Assessment of an Amended Oscillating Water Column Using OpenFOAM release_33yopq6fdjb4zeecptsjqj2txy

Abstract

oscillating water column (OWC) is an advanced form of wave energy converter (WEC). This study aims at improving the efficiency of an amended OWC through a novel methodology for simulating several vertical plates within the chamber. This paper provides a numerical investigation considering one, two, three, and four vertical plates. The open field operation and manipulation (OpenFOAM) solver is verified based on the Reynolds-Averaged Navier–Stokes (RANS) equation. Results show the number and the position of plates where the convertor's efficiency improves. The work undertaken here also revealed a reduction in the net force imposed on the convertor's structure, especially the front wall. Consequently, adding plates acquires more efficiency with lower force on the system.
