  1. 36. 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

  3. 37. 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.

  4. 38. 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

  5. 39. Heat transfer analysis on LED-board in closed environment

    University essay from Malmö universitet/Fakulteten för teknik och samhälle (TS)

    Author : Victor Eneberg; Johannes Linby; [2022]
    Keywords : LED; heat sink; motorcycle; light; headlight; FEM; CFD; IR camera; thermocouple; kylfläns; motorcykel; belysning; halvljus; IR-kamera; thermoelement;

    Abstract : Motorcyclists are more often involved in accidents with severe harm or even fatal outcome compared to other road users. An experienced motorcycle driver is well familiar with the problem when the day light is reduced. The visibility is of course highly decreased. READ MORE

  6. 40. Verification and validation of the implementation of an Algebraic Reynolds-Stress Model for stratified boundary layers

    University essay from KTH/Teknisk mekanik

    Author : Martina Formichetti; [2022]
    Keywords : Atmospheric boundary layer; turbulence modelling; stratified flows; eddy viscosity; eddy diffusivity;

    Abstract : This thesis studies the implementation of an Explicit Algebraic Reynolds-Stress Model(EARSM) for Atmospheric Boundary Layer (ABL) in an open source ComputationalFluid Dynamics (CFD) software, OpenFOAM, following the guidance provided by thewind company ENERCON that aims to make use of this novel model to improvesites’ wind-field predictions. After carefully implementing the model in OpenFOAM,the EARSM implementation is verified and validated by testing it with a stratifiedCouette flow case. READ MORE
