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

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Kaibin Wen; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

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

    University essay from Högskolan Väst/Institutionen för ingenjörsvetenskap

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

    Abstract : 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. READ MORE

  4. 3. Early Stage Design of a Prefilmer at Siemens Energy : Numerical and Experimental Methodology

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Jean-Pierre Hamzo; [2023]
    Keywords : CFD; gas-turbine; computational fluid dynamics; atomizer; prefilmer; RANS; LES; multi-phase; experimental; numerical; atomization; spray characteristics; drop breakup; liquid fuels; liquid films;

    Abstract : Design of atomizers for gas-turbine purposes are an important ordeal. The per-formance of the atomizer directly impacts the efficiency of the gas-turbine, andconsequently, the energy extracted from the turbine. Furthermore, the design ofthe atomizer can have an impact on reducing toxic emissions. READ MORE

  5. 4. An overview of the development and potential of ceramic materials for use in micro gas turbines

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Alexander Ahlqvist Fehr; [2023]
    Keywords : Gas Turbines; Ceramics; Micro Gas Turbines; Gas Turbiner; Keramik; Mikro Gas Turbines;

    Abstract : This paper presents an analysis of the potential of Micro Gas Turbines (MGT) with regards to performance, economic and durability considerations. The performance potential was assessed by calculating the cycle efficiency based on the Brayton cycle and the mechanical efficiency of the expansion turbine. READ MORE

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

    University essay from KTH/Kraft- och värmeteknologi

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

    Abstract : 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. READ MORE
