    Keywords : Wind Turbine; Offshore; Blade; Rotor; Computational Fluid Dynamics; Airfoil; Aerodynamic; Aeroelasticity; Simulation; Fluid; Structure; Interaction; Loads; Control; Response; Harmonics; Vibration; Damping; Flutter; Trailing Edge; Flaps; Wind Gust; Lift; Drag; Unsteady; Pressure; Velocity; Vindkraftverk; offshore; blad; rotor; beräkningsvätske-dynamik; flygplatta; aerodynamisk; aeroelasticitet; simulering; vätska; struktur; interaktion; belastningar; kontroll; respons; övertoner; vibrationer; dämpning; fladdring; bakkant; klaffar; vindstöt; lyft; Drag; ostadig; tryck; hastighet;

    Abstract : Due to the increase of rotor size in horizontal axis wind turbine (HAWT) during the past 25 years in order to achieve higher power output, all wind turbine components and blades in particular, have to withstand higher structural loads. This upscalingproblem could be solved by applying technologies capable of reducing aerodynamic loads the rotor has to withstand, either with passive or active control solutions. READ MORE

  2. 2. Two-dimensional Study of Blade Profiles for a Savonius Wind Turbine

    University essay from Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära; Uppsala universitet/Elektricitetslära

    Author : Johanna Sundberg; Martina Lundberg; Julia Solhed; Aikaterini Manousidou; [2020]
    Keywords : Savonius rotor; vertical axis wind turbines; Ansys Fluent; k-omega SST; overlap ratio; blade arc angle;

    Abstract : A Savonius wind turbine is a self-starting vertical axis rotor. It can be designed to be compact in size and also produces less noise which makes it suitable to integrate into urban spaces such as rooftops and sign-poles. READ MORE

  3. 3. Fretting in Wind Power Pitch Bearings: Micro-Slip Experiments and Bearing Test Rig Design

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Román De La Presilla; [2020]
    Keywords : Fretting; Pitch Bearing; Lubrication.; Fretting; Rotorbladslager; Smörjning;

    Abstract : Wind power is the fastest-growing form of green energy production in Europe, today accounting for 15% of the total power demand with 100.000 turbines installed. READ MORE

  4. 4. Defining, analyzing and determining power losses - due to icing on wind turbine blades

    University essay from Mälardalens högskola/Akademin för ekonomi, samhälle och teknik

    Author : Zandra Canovas Lotthagen; [2020]
    Keywords : Wind Power; De-icing; Defining; Ice losses; Task19; Temperature threshold; Power curve; Big Data;

    Abstract : The wind power industry is one of the fastest-growing renewable energy industries in the world. Since more energy can be extracted from wind when the density is higher, a lot of the investments made in the wind power industry are made in cold climates. But with cold climates come harsh weather conditions such as icing. READ MORE
