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

    University essay from 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. 17. 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. 18. 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

  5. 19. Optimization of wind turbine loads for maximum power output and low fatigue loading

    University essay from KTH/Kraft- och värmeteknologi

    Author : Wondmagegn Ergano; [2020]
    Keywords : ;

    Abstract : In this thesis the aerodynamic loads for maximum power output at acceptable fatigue loads on a 1.5MW onshore wind turbine are examined. READ MORE

  6. 20. A simplified vortex method for wind turbine simulation

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Sandro Malusa; [2019]
    Keywords : Wind turbine; Vortex model; Numerical wake model; Vortex sheet; Vortex filament; Tjaereborg; Biot-Savart law; Iterative method;

    Abstract : A new vortex model for wind turbines was developed in order to evaluate the loads at the blades and other important characteristics of interest for the wind industry such as power and thrust coefficients. Nowadays, the calculation of these quantaties is done in a reliable and precise manner with LES simulation using actuator line or actuator disk models. READ MORE
