  1. 1. Systemdesign för miljövänliga och kostnadseffektiva reservkraftsystem : Undersökning av alternativa reservkraftsystem för en livsmedelsindustri

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Elektricitetslära

    Författare :Philip Clarstedt; [2024]
    Nyckelord :Backup power; Reservkraft; Hybridsystem; Batterilager; Mikrogasturbin; Dieselgenerator;

    Sammanfattning : Backup power is essential to supply important functions in society with electricity in case of a blackout. Today in Sweden most backup generators are based on diesel fuel and seldom used, but they are still associated with bad environmental impact while operating. LÄS MER

  3. 2. Effect of temperature on early stage adhesion during TiAlN sliding against Inconel 718 and Stainless steel 316L : High temperature tribology

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Ahsan Ali; [2023]
    Nyckelord :High temperature tribology; Early-stage adhesion; Adhesive wear; Friction; Wear resistant coatings; Physical vapour deposition PVD coatings; TiAlN; Tungsten carbide WC Co ; Difficult to machine super alloys; Inconel 718; Stainless steel 316L; High-performance materials; Abrasion; Oxidation; Chipping; Ploughing; Characterization;

    Sammanfattning : High-performance materials such as stainless steels and nickel based super alloys are widely used in demanding applications where high mechanical and thermal properties are required. The applications of super alloys are mainly found in jet engines, power plants and gas turbines demanding high fatigue strength, corrosion and oxidation resistance as well as wear resistant properties.

  4. 3. Gear Modifications for Optimal Load Distribution

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Raghunath Adimoolam Ganesan; [2023]
    Nyckelord :Lead correction; Profile correction; Even load distribution; Thermal distortion.; helixkorrigering; profilkorrigering; jämn belastningsfördelning; termisk distorsion.;

    Sammanfattning : In the early days of gear manufacturing, engineers aimed to produce teeth as close to the theoretical shape as possible. As machinery advanced and demand for high-speed, high-torque, and quieter transmissions grew, optimizing gear teeth became increasingly important [1]. LÄS MER

  5. 4. Conceptual design of the next generation gas turbines : Modelling of a hybrid electric mixed turbofan for a trainer aircraft

    Uppsats för yrkesexamina på avancerad nivå, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Sophia Fisher; Michael Åkerström; [2023]
    Nyckelord :Hybrid propulsion; mixed turbofan; parallel configuration; performance;

    Sammanfattning : To mitigate climate change, all sectors must contribute their part. Electric propulsion system is a promising approach to reduce emissions from the aviation industry. A major challenge is however the low energy density in today’s battery technology. LÄS MER

  7. 5. Fuel Transition for Gas Turbines : In a Changing European Energy Landscape

    Master-uppsats, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Lovisa Langerak; [2023]
    Nyckelord :energy technology; gas turbine; energy transition; Europe; green fuels; hydrogen; ammonia; biofuels; energiteknik; gasturbin; energiomställning; Europa; gröna bränslen; vätgas; ammoniak; biobränslen;

    Sammanfattning : The transition to renewable energy sources is vital to mitigate global warming and achieve the climate targets set by the EU. The availability of natural gas in Europe is challenged due to the Russian invasion of Ukraine, leading to a shift towards fossil-free alternatives. LÄS MER
