Abstract
An experiment was designed to create a dataset of wave-current interaction of gravity-capillary waves and currents of similar magnitude to understand how the wave elevation field is modulated by the current. The data product from the experiments will be spatial plots of the wave elevation field of the refracted waves by the current for a range of speeds, headings, and wave periods. The field of view in these spatial plots includes portions of the undisturbed wavefield, a current region of finite width where the waves pass through, and the refracted wavefield on the opposite side of the current.
To verify the experimental design, a “proof of concept” experiment was conducted and confirmed the measurement technique of simultaneous free surface synthetic Schlieren (FS-SS) digital image correlation (DIC) and particle image velocimetry (PIV) measurements is sufficient to measure the wave field elevation of gravity-capillary wave-current interaction at the appropriate spatial resolution and measure associated current velocity.
Data generated from this experimental design will add to, and increase, the scope of existing experimental data related to gravity-capillary wave-current interaction for validation of numerical models.
