An experimental and numerical analysis of an I-beam attenuator-type, oscillating water column wave energy converter

Hydrodynamic analysis of one-way energy capture by an oscillating water column wave energy device

“…The present study is based on the KNSwing device, an I-Beam attenuator, a ship-like structure equipped with 20 oscillating water column chambers on each side, see Nielsen and Bingham (2015). Two-way power absorption, motion response, and mooring loads for the device have been studied, both numerically and experimentally, and reported in: (Bingham et al, 2015b), Bingham et al (2015a) and Nielsen et al (2018). The main purpose of this paper is to present experimental and computational results for a modified version of a single chamber from the KNSwing model which includes a valve system to allow for one-way venting on either the up-or the down-stroke.…”
