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 ... -
An Aeroacoustic Study of Airfoil Self-Noise for Wind Turbine Applications
(University of Waterloo, 2017-04-25)The current study addresses the issue of noise relating to both large and small scale wind turbines. In utility scale applications, larger size rotors in new generations of wind turbines bring an increasing challenge to ... -
Blade Number Influence on Centrifugal Impeller Flow Behavior
(University of Waterloo, 2015-12-10)In this study, experiments were conducted to observe the performance and flow structure of the fluid inside the passage of 5 and 7 bladed impellers. The main purpose is to understand the influence of the number of blades ... -
Comparison of Experimental Methods in the Measurement of Wind Turbine Wakes
(University of Waterloo, 2018-10-22)With the increasing development of wind energy, it has become essential to study the interactions of turbines within wind farms. Wind turbines create wakes when harnessing the energy in the wind for electricity. Reduced ... -
Computational Aeroacoustic Prediction of Airfoil Self-Noise at Static Angles of Attack
(University of Waterloo, 2019-04-17)Aeroacoustic noise from wind turbines is often an obstacle in the implementation of wind farms. Reduction of this noise is key to allowing the expansion of the wind energy sector which is crucial for decreasing the dependence ... -
Quantitative Measurement Techniques for Wind Turbine Blade Aerodynamic Performance
(University of Waterloo, 2017-03-07)The installed capacity of wind turbines has been growing rapidly in recent years, creating an increased need for accurate measurements and models of wind turbine performance to further their development. There is a need ... -
Study of a low Re airfoil considering laminar separation bubbles in static and pitching motion
(University of Waterloo, 2019-01-25)Performance of low Reynolds number (Re) devices is highly dependent on their airfoil design. Small wind turbines that usually work in areas with poor wind resources with a vast application from remote to busy urban regions ...
