  1. 11. 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.

  3. 12. Undertray Design and Development Procedure with CFD : An Optimization Study of Different UndertrayDesigns with CFD Computations

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Aaron Poutiainen; [2021]
    Nyckelord :;

    Sammanfattning : Race car aerodynamics has played a vital part to improve lap times over the years of motor racing. Having good road adhesion with slick tires and aerodynamic downforce will increase the vehicles maximum lateral force and thus higher cornering speeds can be achieved. LÄS MER

  4. 13. Cooling simulation of a BEV electrical machine rotor

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Lisa Sparv; [2021]
    Nyckelord :Electrical machine; Rotor cooling; Permanent magnet; Simulation; STAR-CCM ; Elmaskin; Rotorkylning; Permanentmagnet; Simulering; STAR-CCM ;

    Sammanfattning : The thesis work described in this report is about simulation of the cooling of an electrical machine rotor. Limitations and simplifications were made on the CAD model of the rotor with the purpose of reducing the simulation time, for it to then be used for CFD-simulations using STAR-CCM+. LÄS MER

  5. 14. Conceptual design and construction of a UAV wing structure

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Selma Rahman; Anujan Ranganathan; [2020]
    Nyckelord :;

    Sammanfattning : This report presents the design of the wing structure for a UAV called Skywalker X8. A model of the UAV was given and analyzed to design a wing box structure that is twice the size of the current model, with "greener" technology and lightweight materials. LÄS MER

  7. 15. CFD Simulation of Particles in Pipe Flow and Mixing Tank

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Aljaz Janic; [2020]
    Nyckelord :Multiphase flow; particles; TetraPak; mixing tank; pipe flow;

    Sammanfattning : This project aimed to investigate the capability of the STAR CCM+ software when predicting the flow with particles using Lagrangian Particle Tracking and Discrete Element Method. The first part pertained to rectangular channel flow, with ratio between height of the channel and particle diameter (2h/Dp ) of 15. LÄS MER
