Multi-scale turbulence measurement in the Aquatron laboratory

Principal Investigators:

Dr. Alex Hay, Dalhousie University

Start Date: July 2018

End Date: May 2019

In order for the results from studies of turbine-turbulence-animal interactions in the Aquatron to have application at the field scale, it is essential that the scales of the turbulence in the Aquatron be accurately and comprehensively determined. The proposed project has two primary objectives: (1) to characterize the flow and turbulence in the Aquatron pool tank, using turbulence sensors calibrated against a traceable standard; and (2) to use this facility to test technologies currently under development for investigating the horizontal variability of turbulence in real-world tidal channels. In addition to identifying relationships between turbulence characteristics in the Aquatron and those at the field scale and contributing to the development of new approaches to the measurement of large-eddy turbulence in the field, the results from the proposed project will be directly relevant – and will be made available – to other investigators.
