  1. 1. Environmental Barrier Coatings to protect Ceramic Matrix Composites in next-generation jet engines

    Master-uppsats, Högskolan Väst/Institutionen för ingenjörsvetenskap

    Författare :Shivang Parmar; [2023]
    Nyckelord :Environmental barrier coating; ceramic matric composite; atmospheric plasma spray; suspension plasma spray; thermal cyclic fatigue; Barriärbeläggning; keramisk komposit; atmosfärisk plasmasprutning; suspensionsplasmasprutning; termisk cyklisk utmattning;

    Sammanfattning : Gas turbine engine efficiency needs to be raised in order to decrease fuel consumption, greenhouse gas emissions, and expenses. Efficiency may be improved in two ways: by reducing engine weight and raising intake temperatures. LÄS MER

    Sammanfattning : In order to reduce emissions and achieve sustainable energy systems, renewable energy is increasingly being integrated into the power grid. However, the integration of renewable energy into the grid poses several challenges, including maintaining a stable power supply under changing and unpredictable conditions. LÄS MER

  4. 3. Study on feasibility of small-scale pumped hydro storage- A case study in Sweden

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Prashant Niroula; [2023]
    Nyckelord :energy storage; pumped hydropower; electricity market; investment; new technologies; feasibility; Technology and Engineering;

    Sammanfattning : The European union has been aggressively pushing forward with policies favoring renewable sources of energy. As a result, the share of intermittent renewables in the European power grid is rising and is expected to grow even more in the coming decade. The Swedish energy agency also forecast huge growth in wind power. LÄS MER

  5. 4. Turbulence Intensity Measurements in a High-Pressure Gas Turbine Stage

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Ettore Scami; [2022]
    Nyckelord :Turbulence Intensity; turbine; stage efficiency; grid; turbomachinery; length scales;

    Sammanfattning : This Thesis work focused on the acquisition and evaluation of data on mean velocity, turbulence intensity and length scales obtained via hot wire measurements in a high pressure single-stage land-based turbine available at the Department of Heat and Power Technology in KTH. Turbulence was generated by the use of grids and twoprobes, upstream and downstream of the turbine stage, were used. LÄS MER

  7. 5. Utveckling av ett gränssnitt för ett underhållstödsprotokoll : Användargränssnitt för underhåll på gasturbiner

    M1-uppsats, Linköpings universitet/Institutionen för ekonomisk och industriell utveckling; Linköpings universitet/Tekniska fakulteten

    Författare :Lukas Haglund; Andreas Riis; [2022]
    Nyckelord :;

    Sammanfattning : Siemens Energy AB have for many decades constructed, manufactured and maintained gas turbines but now face a new challenge of systemising and digitalising the maintenance. This will be done by linking the essential information the maintenance engineer needs in a user interface. LÄS MER
