Abstract: Wind turbines operating in cold climate are susceptible to icing events. In order to gain a better understanding of the blade icing, the water droplets local collection efficiency affected by different factors was investigated. ...

Abstract: Icing on wind turbines is a major problem in cold regions. To study blade icing, water droplet collection efficiency is calculated on the National Renewable Energy Laboratory (NREL) phase VI blade. First, water droplet ...

Abstract: The vertical wind shear is one of the major sources of fatigue loads on the blades of a horizontal axis wind turbine. Traditionally, the active individual pitch control system is used to alleviate the cyclic load fluctuations, ...

Abstract: Along with the upscaling tendency, lighter and so more flexible wind turbine blades are introduced for reducing material and manufacturing costs. The flexible blade deforms under aerodynamic loads and in turn affects the ...

Abstract: Aiming at analyzing the wake evolution features of a 3blade vertical axis wind turbine (VAWT), dynamic mode decomposition (DMD) is used to evaluate statistics of the flow field based on unsteady flow field computations. ...

Abstract: Vibration-induced high-cycle fatigue of blades is a prevalent issue in turbomachinery. Blade tip timing (BTT) emerges as a nonintrusive, promising method for assessing blade vibration. Despite its potential, BTT's inherent ...
