  1. 1. 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

  3. 2. Evaluation of potential marine current turbine sites in North American waters

    Kandidat-uppsats, Uppsala universitet/Elektricitetslära

    Författare :Tim Andersson; Muhammad Arsal Akram; Carl-Henrik Carlnäs; Tiffany Salisbury; [2020]
    Nyckelord :vertical axis; marine current turbines; alaska; florida;

    Sammanfattning : Suitable locations for marine current power generation were scouted. The specific turbines considered in this project are vertical axis turbines and require an water velocity of 0.8 m/s to start and has a system efficiency of 20%. LÄS MER

  4. 3. Analysis of Hybrid Offshore Floating Wind and Marine Power

    Magister-uppsats, Högskolan i Halmstad/Akademin för ekonomi, teknik och naturvetenskap

    Författare :Sai Varun kollappillai Murugan; [2018]
    Nyckelord :;

    Sammanfattning : Wind energy is a major part of renewable energy production. With fossil fuel depletion and climate change at the cusp, it is an absolute need to implement or evolve the current source or utilization of renewable energy. The wind has been dominating the onshore for many decades and offshore wind turbines are available at shallow depths. LÄS MER

  5. 4. Tidal park within offshore wind parks : An analysis for the potential use of tidal kites within the Aberdeen offshore wind farm

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Christina Merkai; [2018]
    Nyckelord :tidal energy; tidal kites; offshore wind power;

    Sammanfattning : Offshore wind has proved to be one of the most reliable and clean energy sources over the last few years. The industry has experienced a significant growth, with an increase of 101% only in 2017 compared to 2016. LÄS MER

  7. 5. Spectral Analysis of Flame Emission for Optimization of Combustion Devices on Marine Vessels

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Förbränningsfysik

    Författare :Panagiota Stamatoglou; [2014]
    Nyckelord :Premixed flames; Equivalence ratio; Chemiluminescence; Partial least squared regression; Flame monitoring; Physics and Astronomy;

    Sammanfattning : Chemiluminescent emission from OH*, CH* and C2* radicals and its dependence on the equivalence ratio is being investigated in the current study. The aim of this project is to use the results for combustion control on marine vessels and safety checks. LÄS MER
