  1. 6. Mechanical and thermal buckling analysis of laminated composite plates

    Magister-uppsats, Högskolan i Halmstad/Akademin för företagande, innovation och hållbarhet

    Författare :Aswin Paremmal; Roopak Kuruthukulangara Varghese; [2023]
    Nyckelord :composite material; Mechanical Buckling; Buckling analysis;

    Sammanfattning : Composite laminated structures have many application fields such as aerospace, civil, marine, bio medical, transportation, and mechanical engineering because of their convenience in handling, and very good mechanical properties. Buckling behavior of laminated composite plates subjected to plane loads is indeed an important consideration in the primary design of aircraft and launch vehicle components. LÄS MER

  3. 7. Chemical Kinetic Modeling of the Combustion of NH3/H2 and NH3/syngas Fuel Mixtures Using a Large Amount of Experimental Data

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Andras Szanthoffer; [2022]
    Nyckelord :Ammonia combustion; Detailed chemical kinetic mechanisms; Quantitative mechanism comparison; Local sensitivity analysis; Chemical Physics; Chemistry;

    Sammanfattning : Nowadays, due to the global climate change, it is extremely important to find alternative fuels to reduce the utilization of fossil fuels and the emission of air pollutants such as carbon dioxide (CO2), hydrocarbon pollutants, and soot. Ammonia (NH3) is a promising carbon free fuel candidate that can store and transport renewable hydrogen (H2) energy. LÄS MER

  4. 8. Investigation of the wing design and endurance of an ultralight electrical aircraft

    Master-uppsats, Lunds universitet/Innovation

    Författare :Vanda Ericson; Jonathan Palmgren; [2022]
    Nyckelord :Aerodynamics; Electrical Aviation; CFD; Endurance; Drag; Technology and Engineering;

    Sammanfattning : The goal of this thesis was to explore the conversion of a propeller driven two-seater combustion airplane to an electrical airplane. Four different wing designs were considered. Two variations of Blackwing Sweden AB’s current Blackwing wing (BW), a longer wing (BW-L) and a shorter wing (BW-S), as well as a new wing with a different airfoil (GW). LÄS MER

  5. 9. Geometrical Improvement of Fuel Nozzle Locations in the SGT-750 Gas Turbine : An investigation into fuel-air mixing in main channels 1 & 2

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aryan Delir; [2022]
    Nyckelord :gas turbine engines; turbofan; combustion; SGT-750; flashback; hydrogen; natural gas; premixing; fuel-air mixing; computational fluid dynamics; CFD; turbulence modelling; NOx emission; lean premixed mixture;

    Sammanfattning : This study was conducted on SGT-750, which utilizes can type fourth generation DLE burner, developed at Siemens Energy AB, in Finspång, Sweden. The aim of this study is to obtain a flat fuel profile at the outlet of main channel 1 and main channel 2, demonstrating a proper mixing of fuel and air in the main channels leading to reducing local high-temperature points, and thus, reducing thermal NOx emissions.

  7. 10. Undersökning av ny slamutlastning vid ett reningsverk : Analys av flödesförluster och slampump

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Linus Dovnäs; Gustav Edholm; [2022]
    Nyckelord :sludge; sludge pump; sewage; Slam; slampump; reningsverk; flödesförluster; TS-halt; systemkurva; pumpkurva;

    Sammanfattning : A sewage treatment plant is going to get a station in their plant reconstructed. It is the station where the water is separated from the sludge and then transported out of the plant. This new station is the main area for this project. LÄS MER
