  3. 2. Dynamic simulation and 3D visualization of a floating tilted counter-rotating vertical axis offshore wind turbine

    Kandidat-uppsats,

    Författare :Lovisa Jonsson; Alexander Hedene; Klara Österling; [2023]
    Nyckelord :Wind turbine; Offshore; VAWT; CRVT; Simulation; Visualization; MATLAB; Dynamics;

    Sammanfattning : The growing global demand for clean energy is critical, and wind power plays a crucial role in addressing this need. The increasing demand is driving advancements in the field of offshore wind power and one promising innovation is the counter-rotating vertical axis turbines (CRVT), specifically designed for floating wind power installations.

  4. 3. Modeling of the trajectory of ice thrown from a wind turbine

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Elena Rocchi; [2023]
    Nyckelord :Ice thrown - Ice fall - RANS - LES - CFD - simulations - ballistic model; Technology and Engineering;

    Sammanfattning : There is a growing number of wind turbines installed in cold temperature zones as a result of the restricted space for new construction. Due to ice deposition on the turbine blades, the increasing installation of wind turbines in freezing temperature areas presents many challenges: ice accumulation increases weight, unbalances the rotor, diminishes aerodynamic efficiency, and creates safety issues.

  5. 4. Methods and Purposes of Aerodynamic Correlation in Formula Student

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Alix Le Bastard; [2023]
    Nyckelord :Technology and Engineering;

    Sammanfattning : This thesis investigates how methods of aerodynamic validation can assist a formula student team in designing their aerodynamic package. When de- signing their aerodynamic components, formula student team mostly rely on CFD software simulations, but there is no guarantee that the simulations de- pict properly the physical behaviour of the airflow around the car.
