A Phenomenological Study of Lab-Scale Tidal Turbine Loading under Combined Irregular Wave and Shear Flow Conditions

Tidal devices are likely to faced with shear flows and subjected various wave climates. The paper presents an experimental study of the combined impacts profile irregular waves on loading a 1/20th scale device operating at peak power extraction. experiments presented were conducted depths facilitate analysis effects flow impact positions in water column. fluid field was measured three different upstream (top, middle bottom rotor) for each experiment; doing so, data from captured times. measurements high quality analysed present structure device, which contained velocity turbulence profiles. measurement utilised understand development structures approach confirmed via cross-covariance calculations. long datasets gathered used produce full rotational probability density functions blade-root-bending moments blades. spectral characteristics also considered, showed that rotor quantities less reactive smaller structures.
