  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. 2. Analysis of performance data of wind turbines for polar regions

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Arnau Serra Garet; [2023]
    Nyckelord :;

    Sammanfattning : The Radio Neutrino Observatory in Greenland is situated at Summit Station. Due to its isolatedlocation the main power to support the autonomous radio stations is solar energy. However,during the winter months when there is no sun another strategy needs to be found. LÄS MER

  4. 3. Optimering av Savoniusturbinens effektivitet i marina strömmar med hjälp av CFD-analys av flödesriktare

    Kandidat-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Leonard Hammar; Jacob Kovaleff Malmenstedt; [2022]
    Nyckelord :MCT; Marine Current Turbine; Savonius turbine; CFD; Ansys fluent; diffuser augmented turbine; Savoniusturbin; Marina strömmar; CFD; Ansys fluent; flödesriktare;

    Sammanfattning : The Savonius turbine is a self-starting vertical axis turbine that has a few advantages compared to other vertical axis turbines such as lower cost, lower noise and is relatively easy to manufacture. This turbine does however have a lower efficiency and is therefore less used in the electricity production than other turbines. LÄS MER

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

    Kandidat-uppsats, Uppsala universitet/Elektricitetslära

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

    Sammanfattning : 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. LÄS MER

  7. 5. Nanogrid For Renewable Off-GridSystem : Nanogrid For Renewable Off-GridSystem

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Chukwuebuka Louis Onyia; [2019]
    Nyckelord :;

    Sammanfattning : Power grids utilize large central generating stations which entails the use of long transmission lines to deliver power to consumers. This approach poses some challenges such as line loses and carbon dioxide (CO2) emission into the environment from the burning of fossil fuels from such large generators. LÄS MER
