Multi-Scale Turbulence Measurement in the Aquatron Laboratory

July 2018 – July 2019

This project has two primary objectives - to characterize the flow and turbulence in the Aquatron facility pool tank using turbulence sensors calibrated against a traceable standard; and to test technologies for investigating the horizontal variability of turbulence in real-world tidal channels.

Remote Acoustic Measurements of Turbulence in High-Flow Tidal Channels during High Wave Conditions

April 2018 – April 2019

Many of the high-flow tidal channels targeted for worldwide in-stream hydro-electric development are impacted by surface gravity waves incident from a large exterior basin (e.g. the Bay of Fundy/Gulf of Maine/North Atlantic).

Turbine Wake Characterization

November 2017 – March 2019

Turbine wake characterization is a key endeavour to the development of in-stream tidal turbine arrays.  In a sense, a turbine’s footprint includes its wake, wherein flow speeds are less and turbulence is elevated compared to the ambient surroundings.  It is thus desired to not just delineate wake

Going with the Flow II: Using Drifters to Address Uncertainties in the Spatial Variation of Tidal Flows

October 2017 – June 2018

Drifters are one of the oldest, simplest and most reliable methods for measuring ocean currents. Drifters also provide a simple, low risk platform from which to gather acoustic information along flow streamlines or ‘drift tracks’.

Tidal Energy: Strategic Environmental Assessment – Bay of Fundy (Phase I)

April 2018

This Strategic Environmental Assessment (SEA) provides advice on whether, when and under what conditions tidal energy demonstration and commercial projects should be allowed in the Bay of Fundy.

Nova Scotia Small Tidal Test Centre: Gap Analysis and Business Case

November 2017 – March 2018

As the tidal energy industry develops, there is increasing interest in the prospects for small-scale tidal energy development. Building small-scale tidal energy installations has promise given the number of locations where they can be used.

Numerical Modeling of Tidal Turbine Behaviour under Real Turbulent Tidal Flow Conditions

December 2015 – December 2016

Researchers investigated and numerically quantified the behaviour of a tidal turbine under turbulent unsteady tidal flow, using flow data collected in the lower Bay of Fundy (Digby area).

Turbulence in Grand Passage Nova Scotia: Measures of Intermittency

April – December 2016

Turbulence research is very important to advancing the in-stream tidal energy sector, however turbulence in general is not well understood.  Measurement at prospective turbine locations is essential prior to development, given the high degree of spatial variability between sites.

Nova Scotia Tidal Research Summary Report – Researching Tidal Energy – Marine Life: The Nova Scotia Experience

October 2015 – May 2016

This report looks at the extensive tidal energy-related research undertaken in the Bay of Fundy over a 10 year period beginning in 2005.

Characterizing Tidal Flows and Turbine Power Production in Petit Passage using Oceanographic and CFD Models

September 2015 – March 2016

The goal of this project was to identify potential turbine deployment locations in Petit Passage Nova Scotia, using computational fluid dynamics (CFD) and finite volume coastal ocean models (FVCOM).
