Abstract

A stationary cylindrical oscillating water column (OWC) wave energy converter (WEC) that has a concentric multi-chamber configuration is proposed. Based on the linear potential flow theory and the eigenfunction matching method, a mathematical model is developed to investigate the hydrodynamics of the multi-chamber OWC WEC. The effect of the sub-chamber number on the hydrodynamic efficiency is investigated. The free-surface oscillation modes inside the chambers are discussed, with the piston-type mode making the main contribution to the energy conversion. The effects of geometric parameters on the hydrodynamic characteristics are also further investigated. It is found that the effective bandwidth of the device with the same sub-chamber width/radius is almost identical when the number of sub-chamber is greater than three. The sub-chamber number has no significant effect on the effective frequency bandwidth with the same total chamber width. A shorter outermost shell draft and a wider chamber width can enhance the capability for wave power extraction.
