  1. 1. Design Optimization of Savonius Wind Turbine using CFD Simulations

    Master-uppsats, Uppsala universitet/Institutionen för elektroteknik

    Författare :Vatsalkumar Manavar; [2023]
    Nyckelord :Savonius wind turbine; Computational fluid dynamics; Vertical axis wind turbine; Overlap ratio; Distance between blades; Power coefficient;

    Sammanfattning : This thesis is based on a simulation of the Savonius wind turbine. The Savoniusturbine is a simple vertical axis device, which has half cylindrical blades attached to the main shaft opposite to each other which creates the drag force from incoming wind and generates mechanical torque which drives the generator for electricity generation.

  3. 3. Design of wind turbine blades with respect to stability

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Byggnadsmekanik

    Författare :Oskar Lindkvist; Victor Nicolausson; [2019]
    Nyckelord :FEM; Buckling; Stability; Wind turbine blades; Steel.; Technology and Engineering;

    Sammanfattning : In the 21st century, wind power has emerged as a strong candidate in fulfilling societies goals of achieving carbon-free energy energy production. Windpower has evolved along with other technological developments, giving rise to larger turbines, but with the overall design trend remaining largely unchanged. LÄS MER

  4. 4. Experimental investigation of a de-icing system for wind turbine blades based on infrared radiation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Sofia Sollén; Jennifer Pettersson; [2019]
    Nyckelord :Wind power; Wind turbine; Cold climate; Ice and snow; De-icing; De-icing system; Infrared radiation; Infrared heater.;

    Sammanfattning : Wind power is one of the fastest growing production methods of electric energy. The expansion of wind power in Sweden are focused to northern counties. There are advantages as good wind conditions and large unexploited areas to build wind farms in the north, but there are also problems caused by the long winters. LÄS MER

  5. 5. Killer Robots - Autonomous Weapons and Their Compliance with IHL

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Juridiska institutionen

    Författare :Cecilia Andersson; [2014]
    Nyckelord :autonoma vapen; international humanitärrätt; robots. Folkrätt; autonomous weapons; Public international law; International humanitarian law; robotar.; Law and Political Science;

    Sammanfattning : The pursuit of weapons which distance the soldier from the actual battlefield has been going on ever since the transition from the waging of war using short blades, to the waging of war using bow and arrow. Today, that ambition has reached an almost completion with the ever-increasing number of unmanned, remote-controlled vehicles that are rapidly becoming the most common and prominent method of waging wars.
