Active Aerodynamic Modification of Wind Turbine Blades to Reduce Load Fluctuation
(University of Waterloo, 2020-04-16)Wind turbines operate predominantly in relatively unsteady flow conditions and are typically misaligned with the incoming wind. Moreover, as wind turbines increase in size, the loading on the blades becomes more problematic ... -
Analysis of a Clean Energy Hub Interfaced with a Fleet of Plug-in Fuel Cell Vehicles
(University of Waterloo, 2011-01-24)The ‘hydrogen economy’ represents an energy system in which hydrogen and electricity are the dominant energy carriers for use in transportation applications. The ‘hydrogen economy’ minimizes the use of fossil fuels in order ... -
Development of a Wind Turbine Test Rig and Rotor for Trailing Edge Flap Investigation
(University of Waterloo, 2014-05-16)Alleviating loads on a wind turbine blades would allow a reduction in weight, and potentially increase the size and lifespan of rotors. Trailing edge flaps are one technology proposed for changing the aerodynamic characteristics ... -
Digital Tuft Flow Visualisation of Wind Turbine Blade Stall
(University of Waterloo, 2014-05-20)Wind turbines installed in the open atmosphere experience much more complex and highly-varying flow than their counterparts in wind tunnels or numerical simulations. In particular, aerodynamic stall—which occurs often on ... -
Dynamic Stall on Pitching Cambered Airfoil with Phase Offset Trailing Edge Flap
(American Institute of Aeronautics and Astronautics (AIAA), 2020-04-20)Dynamic stall on wind turbine blades often leads to severe fatigue that tends to decrease the lifespan of the blades. To mitigate cyclic loading on the blades, trailing edge flaps (TEF) may be used to control the energy ... -
An Evaluation Testbed for Alternative Wind Turbine Blade Tip Designs
(University of Waterloo, 2011-05-19)The majority of present-day horizontal axis wind turbine blade tips are simple designs based on historical trends. There is, however, some evidence that varying the design of the tip can result in significant changes in ... -
Investing Flow over an Airfoil at Low Reynolds Numbers Using Novel Time-Resolved Surface Pressure Measurements
(University of Waterloo, 2011-04-12)An aluminum NACA 0018 airfoil testbed was constructed with 95 static pressure taps and 25 embedded microphones to enable novel time-resolved measurements of surface pressure. The main objective of this investigation is to ... -
Predictive Maintenance of Wind Generators based on AI Techniques
(University of Waterloo, 2019-12-17)As global warming is slowly becoming a dangerous reality, governments and private institutions are introducing policies to minimize it. Those policies have led to the development and deployment of Renewable Energy Sources ...
