  1. 1. Flow modeling and bank erosion downstream due to spillway discharge : Independent thesis Advanced level (professional degree) 30 ECTS credits

    University essay from Uppsala universitet/Avdelningen för beräkningsvetenskap

    Author : Alexander Lindblad; [2022]
    Keywords : Ansys Fluent; Multiphase Flow; Spillway; CFD; Volume of Fluid; Reynolds-averaged Navier-Stokes;

    Abstract : Dam spillways and downstream areas are used to guide large flows of water during for example heavy rainfall. The large flows give way to turbulent pattern sand velocities that may damage the river banks or the dam structure. Investigation of these water patterns at certain flows are therefore done to examine at risk areas. READ MORE

  3. 2. Aerodynamic Analysis of Reflex Airfoils at Low Reynolds Numbers

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Alexander Elliott Meyer Ströborg; [2022]
    Keywords : low Reynolds number; reflex airfoils; CFD; XFOIL;

    Abstract : Low Reynolds number airfoil analysis has become increasingly significant as urban air mobility vehicles and unmanned aerial vehicles surge in popularity. The Green Raven project at KTH Aero aims to use reflex airfoils where little data is available beyond classical analysis. READ MORE

  4. 3. Modelling Gas Flow Behaviour in Gas Atomizer

    University essay from KTH/Materialvetenskap

    Author : Aravind Senan Vasanthasenan Reji; [2022]
    Keywords : Gas atomization; Nozzle; Velocity; Static pressure; Discrete phase model; Gasatomisering; Munstycke; Hastighet; Statiskt tryck; Diskret fasmodell;

    Abstract : Gas atomization is regarded as a reliable method for creating high-quality metal powders from molten metal. The liquid metal is fed into the chamber as a free-falling stream through a nozzle, where it is impinged by high-velocity gas jets, causing degeneration and production of metal droplets, which solidify to create metal powders.

  5. 4. Optimization and Additive Manufacturing for HPGP Rocket Engines

    University essay from KTH/Kraft- och värmeteknologi

    Author : Jessie Stachowicz; [2022]
    Keywords : Additive Manufacturing; Rocket Propulsion; Nozzle Design; Computational Fluid Dynamics; CFD; Nasa CEA; DED; PBF; High Performance Gas Propulsion; ADNbasedPropellant; CD Nozzle; Additiv tillverkning; raketframdrivningssytem; munstycksdesign; beräkningsflödesanalys; CFD; Nasa CEA; DED; PBF; högpresterande gasframdrivning; ADNbasedPropellant; Konvergerande-divergerande munstycken;

    Abstract : This thesis aims to investigate whether additive manufacturing is applicable in manufacturing the 1N thruster option that Bradford Ecaps offers. Therefore, the nozzle design is of particular interest as AM provides accessibilities to manufacturing complex structures. READ MORE

  6. 5. Hydrogen-Methane combustion modeling in the burner of the SGT-800 Siemens Energy gas turbine

    University essay from KTH/Teknisk mekanik

    Author : Nikolaos Bozikis; [2022]
    Keywords : Engineering mechanics; fluid dynamics; CFD; combustion modeling; industrial gas turbines;

    Abstract : Industrial gas turbines constitute an integral part of today’s electricalpower production infrastructure. Reacting gas flows in these machines arevery interesting and complex in nature since they exhibit highly turbulentbehaviour which is strongly coupled to the chemical reaction dynamics. READ MORE
