Test tank to tidal channel: improved turbine load predictions

The recently completed InSTREAM project assessed fundamental differences in turbulent flow measured in the field, generated in a tank and simulated in a numerical model. InSTREAM processes enables site-specific field measurements to be translated to tank experiments, enabling numerical models (validated by tank experiments) to be used for reliable and realistic estimation of turbine and array performance.

In Situ Turbulence Replication Evaluation And Measurement (InSTREAM).

Instrumentation set-up for test tank

The flow through tidal passages is, by nature, extremely turbulent and this variability in flow speed affects the efficiency of energy extraction and the operational risks for in-stream turbines. The accurate measurement and numerical modeling of turbulence for these conditions will de-risk  the design and development of tidal energy sites and reduce their cost of operation.

A collaborative Canadian - UK research project, In Situ Turbulence Replication Evaluation And Measurement (InSTREAM ...
