Characterization of turbulence anisotropy, coherence, and intermittency at a prospective tidal energy site: Observational data analysis
As interest in marine renewable energy increases, observations are crucial for understanding the environments that prospective turbines will encounter. Data from an acoustic Doppler velocimeter in Puget Sound, WA are used to perform a detailed characterization of the turbulent flow encountered by a turbine in a tidal strait. Metrics such as turbulence intensity, structure functions, probability...
متن کاملField measurements of unsteady turbulence in a tidal bore: the Garonne river in October 2013
A tidal bore is an unsteady rapidly-varied open channel flow generated by the swift advance of the early flood tide in a funnel-shaped river estuary when the tidal range exceeds 4.5 to 6 m. This contribution presents a detailed field investigation conducted on the tidal bore of the Garonne River (France). The bore was undular and the bore’s leading edge was followed by well-defined secondary wa...

متن کاملUnsteady Turbulence in a Tidal Bore: Field Measurements in the Garonne River in October 2013
A tidal bore is an unsteady rapidly-varied free-surface flow generated by the rapid rise in water elevation during the early flood tide, when the tidal range exceeds 4.5 to 6 m and the channel bathymetry amplifies the flood tidal wave. This study describes a detailed field investigation conducted in the Garonne River (France). The tidal bore was undular on 19 October 2013 and the bore front was...
متن کاملImplications of Tidal Phasing for Power Generation at a Tidal Energy Site
Spatial resource gradients have been observed at a number of proposed tidal energy sites. However, these gradients are typically quantified using the first or second moments (i.e., mean or standard deviation) of time series which obscures information about the co‐temporal amplitude and phase variation. These co‐temporal variations have a number of interesting implications for power production f...
