  1. 1. Development of a System to Quantify Coking in Rocket Nozzle Cooling Channels

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

    Författare :Adam Parks; [2022]
    Nyckelord :methane; pyrolysis; reusable; carbon deposition; ozone cleaning; rocket engines; cooling channels; borescope; metan; pyrolys; återanvändbar; koldeposition; ozon-rening; raketmotorer; kylkanaler; boreskop;

    Sammanfattning : Liquid methane is becoming an increasingly attractive rocket propellant due to its high performance characteristics and potential to support in-situ resource utilisation. Methane, however, when heated, can thermally decompose in a process known as pyrolysis. LÄS MER

  3. 2. Insights into the burning behaviour of wood in the cone calorimeter

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Ellinor Sanned; [2022]
    Nyckelord :Wood combustion; fire test; cone calorimetry; heat release rate; char formation;

    Sammanfattning : Climate change and its accompanying environmental issues have caused the building industry to use more environmentally friendly building materials. Wood have always been a buildingmaterial but due to the renewed interest in imparting sustainability and renewability, its usage has increased over the recent years. LÄS MER

  4. 3. Fabricability of a high alloy tool steel produced with LPBF, with a focus on part geometry

    Master-uppsats, Karlstads universitet

    Författare :Zulfaqar Abdelamir; [2021]
    Nyckelord :Addtive Manufacturing; Laser Powder Bed Fusion; High alloy Cold Work Tool Steel; Addtiv Tillverkning; LPBF; Höglegerat kallbearbetningsstål;

    Sammanfattning : Additive manufacturing (AM) is a promising manufacturing process that provides that ability to fabricate components with complex geometries with relatively low lead times compared to other manufacturing processes. This allows for more freedom of design, as prototypes can easily be produced throughout the development process. LÄS MER

  5. 4. Utredning av sprickorsakerna i infästningarna till kylelement

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för ingenjörsvetenskap

    Författare :Ammie Bäckström; Nicklas Werner; [2021]
    Nyckelord :;

    Sammanfattning : The assignment handed out by Cementa in Skövde is to investigate why crack formation and propagation emerge in the fixed attachment clamps and propose solutions against it. The fixed attachments are part of the cooling element suspension, used in the cement production to cool the material coming out of the oven. LÄS MER

  7. 5. Erosion Behaviour of Thermal Barrier Coatings

    Master-uppsats, Linköpings universitet/Konstruktionsmaterial

    Författare :Caroline Wännman; [2021]
    Nyckelord :erosion; TBC; APS; EB-PVD; PS-PVD; failure mechanisms;

    Sammanfattning : Thermal barrier coatings (TBCs) are advanced material systems used in the hot sections of gas turbines. The TBCs are designed to provide insulation against hot gases by a ceramic top coat and to provide oxidation and corrosion resistance by a metallic bond coat. LÄS MER
