  1. 16. Developement of a numeric tool for fatigue life evaluation of the regulating mechanism in Kaplan runners

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Emil Treitler; [2022]
    Keywords : Fatigue; Kaplan; Hydropower; Turbine;

    Abstract : Kaplan turbines are a type of hydropower turbine with adjustable runner blades. This allows the turbine to alter its power output while maintaining a relatively high efficiency over a wide range of power levels. But these frequent blade angel adjustments exposes the turbines internal mechanism to wear and the possibility of fatigue failure. READ MORE

  5. 19. QUANTIFYING ERRORS IN PITCH ANGLE POSITION USING BEM THEORY

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Sai Varun Kollappillai Murugan; [2021]
    Keywords : NREL; Qblade; SCADA; Pitch angle errors; Wind turbines;

    Abstract : The wind industry is always seeking ways to better understand the performance of a wind turbine and improve its efficiency. During the operation phase and maintenance, wind turbines go through regular optimization. Due to the regular change in wind speed and direction, wind turbines need to be regulated and positioned accordingly. READ MORE

  6. 20. Modeling of Precipitation by Structural Phase-Field Crystal Method

    University essay from Malmö universitet/Institutionen för materialvetenskap och tillämpad matematik (MTM)

    Author : Jacob Holmberg-Kasa; [2021]
    Keywords : strain-age cracking; SAC; structural phase-field crystal; XPFC; nickel-based alloys; precipitation;

    Abstract : Nickel-based alloys are used in components such gas turbines within the aerospace industry and electric power generation due to its high tensile, rapture and creep strength. Increasing the efficiency of gas turbines are crucial to reduce emissions within the aerospace industry and increasing power gain for electric power generation. READ MORE
