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’.
In Situ Turbulence Replication and Measurement (InSTREAM)
October 2015 – January 2018
The In Situ Turbulence Replication and Measurement (InSTREAM) project was conceived to address some fundamental questions about the turbulence physics in tidal energy sites and laboratory tanks used to simulate these sites.
Turbulence Dissipation Rates from Horizontal Velocity Profiles at Mid-Depth in Fast Tidal Flows
December 2017
This study characterizes the turbulence in a tidal channel in the Bay of Fundy that has been identified for development as a tidal power resource.
Going with the Flow: Advancement of Drifting Platforms for use in Tidal Energy Site Assessment & Environmental Monitoring
April 2015 – August 2017
This research project aimed to apply a simple and low cost philosophy to ocean observation by developing an inexpensive low-profile surface drifter for use in initial assessment of potential tidal energy development opportunities. The project addressed limitations in the existing drifter design
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.
FORCE Data Management System/User Interface
April – June 2017
This project defined a Data Management System (DMS) and user interface solution for use by FORCE.
Impact of Channel Blockage on the Performance of Axial and Cross-Flow Hydrokinetic Turbines
April 2017
This work investigates the effect of channel blockage on how axial and cross-flow turbines perform. The objective is to fill a gap in the literature on suitable blockage corrections for cross-flow turbines.
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.
High-Resolution Numerical Model Resource Assessment of Minas Passage, Bay of Fundy
January 2017
Two numerical models developed by the Acadia Tidal Energy Institute are described. The models simulate the tidal flow in the Bay of Fundy, and in particular the Minas Passage. The models have different grid resolution, one suitable for site assessment and one suitable for resource assessment.
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).
