The Vectron2 Project: Turbulence Measurements for the In-stream Tidal Energy Industry
March 2019 – November 2021
The Vectron is a new sensor used for measuring turbulence velocity within a tidal turbine’s swept area. The Vectron has been successfully prototyped, where next steps are to take the technology to the ‘industry-ready’ stage of development and the focus of this project.
Real-Time Detection of Marine Mammals in High Flow Environments
May 2019 – September 2021
The project research goal is to design and test an innovative acoustic sensor system that will feature a wireless magneto-inductive (MI) communications link – to alert users in real time of the presence and location of marine mammals in high noise tidal environments. The research entails a field
Development of Acoustic Doppler Aquatic Animal Monitoring (ADAAM) for application to marine life movement in high-energy tidal channels
March 2018 – February 2021
Acoustic Doppler Current Profilers (ADCPs) are a standard tool used for measuring ocean currents.
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.
Use of Fish Tracking Data to Model Striped Bass Turbine Encounter Probability in Minas Passage
September 2016
This project used fish tracking datasets and VEMCO detection-range tests to calculate fish-turbine encounter probabilities for striped bass.
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.
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.
