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.

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).

On-line Interactive GIS Map Platform: An Enabling Initiative for the Emerging Tidal Energy Industry

April 2015 – April 2016

A proof-of-concept Geographic Information System (GIS) platform was developed aiming at building a decision-making tool that integrates complex spatial information of importance to the tidal energy industry while also being scalable, flexible and accessible.  The platform was built on open source

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).

Spectral and Structure Function Estimates of Turbulence Dissipation Rates in a High Flow Tidal Channel Using Broadband ADCPs

January 2016

Spectral and structure function methods are implemented to compute the dissipation rate, ε, from broadband, diverging-beam, acoustic Doppler current profiler (ADCP) data collected at four sites in a high-flow tidal channel.

Development of High Performance Tidal Turbine Rotors

January 2013 – October 2015

This research investigated and informed novel and cost-effective engineering solutions to extract and deliver energy from tidal flows.

Turbulent Scale and Wake Modeling on a Horizontal Axis Turbine

January – April 2015

This project aimed to accurately simulate turbulent flow over a scaled horizontal axis tidal turbine to resolve turbulence in the near and far field regions.

Turbulence and Bottom Stress in Minas Passage and Grand Passage

September 2011 – February 2015

This project aimed to investigate turbulence and bottom stress at two sites being targeted for in-stream tidal power development in Nova Scotia: Minas Passage in the Upper Bay of Fundy and Grand Passage, located between Brier and Long Island in the lower Bay of Fundy.

Seasonal Erodibility of Sediment in the Upper Bay of Fundy

February 2012 – January 2015

This project developed methods for studying sedimentation to the macro-tidal flats of the upper Bay of Fundy. The researchers looked at seasonal variation in the erodibility of sediments in tidal creeks and flats using a Gust Erosion Chamber and repeated grain size surveys.

Observations of Marine Mammals in Petit Passage and Grand Passage, Nova Scotia and Adjacent Waters in the Eastern Bay of Fundy to Assess Species Composition, Distribution, Number and Seasonality.

June – December 2014

This research project implemented a common mobile tool, database, and alert system for recording and acting on marine life sightings, while engaging coastal communities in protection of the marine environment and using crowd-sourcing to collect data for scientific research.
