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: This paper presents tests of an antisurge system based on pressure derivatives. The control algorithm was proven to work on different machines and with different unstable flow phenomena. Compressors are known to be affected ...
