  1. 1. Evaluation of Swedish daylight regulations in university building - Validation and applicability

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Cédric Berthou; [2024]
    Nyckelord :Daylight; Sweden; University building; modelling; Grasshopper; building performance simulation; Dagsljus; svenska föreskrifter; universitetsbyggnad; 3D-modellering; Grasshopper;

    Sammanfattning : Daylight availability in buildings faces numerous challenges in a world where energy efficiency,thermal comfort, and sustainability take center stage. Daylight is well-known for its role in reducingartificial lighting consumption and enhancing the well-being and performance of building occupants. LÄS MER

  3. 2. 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

  4. 3. InclusiveRender A metaverse Engine prototype to support Accessible Environments for people with ASD

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Oscar Borg; Niklas Enberg; [2023]
    Nyckelord :metaverse; Autism Spectrum Disorder; Virtual Reality; Immersive Learning; Personalised Learning; Machine Learning; Accessibility;

    Sammanfattning : The metaverse has seen increased usages in its capabilities as an educational tool by immersing users in virtual scenarios. This technology is inaccessible for user groups that require higher degrees of accessibility and personalization, as most metaverse implementations do not adjust to the user’s needs. LÄS MER

  5. 4. Design of Experiment Based on Full Factorial CFD Spray Modelling

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Olle Faritzon; [2023]
    Nyckelord :CFD; spray; liquid; injection; DoE; Design of Experiment; fuel spray; Propane; LPG; OpenFOAM; Experiment; Fluid dynamics; maritime shipping; engine; Technology and Engineering;

    Sammanfattning : Design of experiment is a powerful tool that can reduce the amount of physical testing needed to save resources, time and money. A CFD-setup was constructed in OpenFOAM-8, simulating injection of liquid propane with a standard multi-hole injector. The model was then validated against experimental results. LÄS MER

  7. 5. Experimental study on the effect of rocket nozzle wall materials on the stability of methane

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

    Författare :Thomas L. Holmboe; [2023]
    Nyckelord :Methane; pyrolysis; catalysis; nickel; coke deposition; chemical modelling; GRI3.0; rocket nozzle; regenerative cooling;

    Sammanfattning : There has recently been an increased interest in methane as a rocket propellant due to its physical properties as well as the possibility of in-situ resource utilization in places like Mars. As part of ESA’s Future Launcher Preparatory Program, KTH in cooperation with GKN Aerospace has started the MERiT program, which seeks to study the characteristics of methane under conditions found in rocket nozzle cooling channels.
