Drones and Drifters – The Great Pumpkin Race
October 2016 – July 2017
This project tested and developed a new low-cost approach to collecting oceanographic measurements for use in tidal initial site assessments. The plan combines one of the oldest tools in oceanography, the drifter, with one of the newest, the drone.
Advancing Tidal Energy Turbine Operations through High Fidelity Tug Propulsion and Control Simulation Software
November 2016 – March 2017
The project objective was to develop a numerical model of a tug boat and its propulsion system to accurately predict its dynamic behaviour in turbulent tidal flows.
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.
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.
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.
Turbulence and Drag in a High Reynolds Number Tidal Passage Targeted for In-Stream Tidal Power
August 2013
Results are presented from an investigation of turbulence and bottom drag carried out in Grand Passage, lower Bay of Fundy.
Impacts of Tidal Energy Extraction on Sediment Dynamics in Minas Basin, Bay of Fundy
February 2010 – December 2012
Researchers developed a numerical hydrodynamic and sediment transport model for Minas Basin in the Bay of Fundy, focusing on the sediment dynamics of the tidal inlets and flats.
Tidal Energy Resource Assessment Map for Nova Scotia
March – October 2012
This project used numerical simulations and theoretical calculations to predict not only the power that can be extracted from the flow through a passage but also the reduction in flow through the passage.
Effects of Energy Extraction on Sediment Dynamics in Intertidal Ecosystems of the Minas Basin
January 2010 – May 2012
This project assessed how the dynamics of sedimentation change when energy is extracted from a macro-tidal system. The differences in tidal prism and energy between neap and spring tidal cycles were used as a proxy for energy extraction by in-stream tidal power devices.
