  1. 21. Thermal Investigation of the Green Revolution Energy Converter : A study on the heat transfer within the GREC in regards of temperature distribution and heat rate

    L3-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Wilma Fager; Maja Abrahamsson Bolstad; Emma Gustafsson; Emma Andersson; Matilda Eriksson; [2023]
    Nyckelord :GREC; Energy; Heat transfer; Heat rate; Temperature distribution;

    Sammanfattning : To reduce emissions, new technological solutions can be of use. One technology which is currently being developed is the Green Revolution Energy Converter, GREC. GREC is an engine with the aim to produce electricity from temperature gradients.  This project is part of a greater project that is divided in two with different focus areas. LÄS MER

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

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

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

    Sammanfattning : 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. LÄS MER

  4. 23. Development of HVAC simulations for truck cabins using OpenFOAM

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Junaid Haider; [2023]
    Nyckelord :Computational Fluid Dynamics; OpenFOAM; Conjugate Heat Transfer; chtMultiRegionFoam;

    Sammanfattning : In regions with cold climates, a layer of ice often forms on vehicle windshields, whichobstructs the driver’s view. To address this issue, vehicles are equipped with internal defrosters. However, at Scania, the evaluation of defroster design performancecurrently relies on time-consuming and costly physical testing. LÄS MER

  5. 24. Input shaping in a cantilever 3D printer : Construction and evaluation

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

    Författare :Albert Achrén; Jacob Bårdén; [2023]
    Nyckelord :FDM; 3D printing; input shaping; cantilever; additive manufacturing; FDM; 3D Printing; inout shaping; fribärande; additiv tillverkning;

    Sammanfattning : FDM 3D printing is an additive manufacturing technology that is widely used, mainly for rapid prototyping. It is also one of the cheapest and most accessible AM technologies for consumers. FDM printers, and especially cheaper alternatives, can have problems with creating high quality prints. LÄS MER

  7. 25. Design and construction of an access concept for a tow bar mounted cargo box : Analysis and development of the user experience

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

    Författare :Oskar Hildestrand; Emma Karlberg; [2023]
    Nyckelord :Backbox; Tow bar cargo box; Product analysis; User-centered design; User experience; Product Design; Mechanical Design and Combination lock; Bakbox; Dragkroksbox; Produkt analys; Användarcentrerad design; Användarupplevelse; Produkt design; Mekanisk konstruktion; Kombinationslås;

    Sammanfattning : Due to the climate crisis, electrical vehicles are on the upswing. To optimize the range of electric cars, aerodynamics is an important factor to consider. Therefore, cargo boxes mounted on the tow bar, often called backboxes, have become an interesting alternative to the standard roof mounted cargo box. LÄS MER
