Floating Wave Amplifier regular-wave basin experiment: wave-field, structural-motion, nonlinear phase-coupling, and WAMIT validation data

Published by Oregon State University | Department of Energy | Catalog Last Checked: September 10, 2026 at 05:53 PM | Dataset Last Updated: August 10, 2026 at 03:34 PM
This dataset supports an experimental investigation of a V-shaped Floating Wave Amplifier (FWA) composed of two submerged flexible circular fabric beams. The experiments were conducted in the O.H. Hinsdale Large Wave Basin at Oregon State University. Synchronized resistive wave-gauge and Qualisys optical-motion measurements characterize the incident-wave proxy, local free-surface motion, whole-beam motion, and residual structural deformation over a regular-wave campaign spanning water depths of 0.50-1.00 m, commanded wave periods of 0.80-2.00 s, and incident headings of 0-20 degrees. This submission includes native instrument records, processed Qualisys and wave-gauge MATLAB files, case metadata, completed experimental and simulation validation objects, publicly redistributable WAMIT inputs and derived first-order outputs, analysis code, figure-source tables, and reproducibility manifests. The associated paper uses 56 retained regular-wave cases and 319 valid case-field observations to evaluate local wave-height amplification, upwave/downwave redistribution, relative-diameter scaling, carrier-band whole-beam and deformation associations, second- and third-harmonic energy, bispectral phase coupling, and a two-body first-order WAMIT baseline. The upstream wmwg15 gauge is treated as an incident-wave proxy rather than a direct wavemaker measurement. Early-arrival windows are provided for incident harmonic assessment so that later FWA- and basin-reflected energy is excluded as far as travel-time estimates permit. The WAMIT products are linear, first-order radiation/diffraction results and do not reproduce nonlinear superharmonics. Documentation identifies the paper subset, data hierarchy, coordinate transformations, units, variable conventions, limitations, and steps required to reproduce the reported outputs.
