  1. 1. Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography

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

    Författare :Kaibin Wen; [2023]
    Nyckelord :Investigation of Roughness Effects on Heat Transfer of Upscaled Additively Manufactured Channels in the Turbulent Region Using Infrared Thermography; Additiv tillverkning; värmeöverföring; infraröd termografi; ytjämnhet; finita elementmetoden;

    Sammanfattning : Additive manufacturing (AM) has largely improved design freedom compared with traditional manufacturing processes such as casting and milling. The layer-by-layer workflow makes it possible to produce objects with much more complex shapes and structures. LÄS MER

  3. 2. 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

  4. 3. Microstructural design and optimization of Nickel-based superalloys for gas turbines

    Master-uppsats, KTH/Materialvetenskap

    Författare :Anirudh Vasishta; [2023]
    Nyckelord :Nickel- based superalloys; gamma prime γ′ size calculations; Nickelbaserade superlegeringar; gamma prime γ′ storleksberäkningar;

    Sammanfattning : One of the main sources of energy in this modern world is the gas turbine.  They reach extremely high working temperatures at peak capacity and hence require materials that can withstand the same. LÄS MER

  5. 4. 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

  7. 5. Automated High-Temperature Pressure Sensor Verification and Characterization

    Master-uppsats, Linköpings universitet/Institutionen för systemteknik

    Författare :Algirdas Bartkevicius; [2023]
    Nyckelord :Pressure sensor; sensor verification; sensor characterization; piezoelectric sensor; dynamic pressure sensor;

    Sammanfattning : Gas turbines are widely used in power generation. Monitoring pressure variations in the combustion chamber allows for real-time assessment of the turbines performance, and can be used to optimize combustion processes, leading to reduced emissions. LÄS MER
