  1. 1. Computational Fluid Dynamics and Modeling of a Free Surface Flow

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

    Författare :Mathieu Marmier; [2023]
    Nyckelord :CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Sammanfattning : This project deals with the CFD modelling of a free surface flow. The aim is to develop and validate a fast and accurate numerical model for stratified two-phase flows. Volume of Fluid (VOF) multiphase model is employed. The purpose is to use the developed numerical model for the design of an element within a compact nuclear reactor. LÄS MER

  3. 2. SECOND-ORDER DIVERGENCE-FREE FEM FOR MAGNETOHYDRODYNAMICS USING LAGRANGE POLYNOMIALS

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Erik Björklund; Peter Mårtensson; Noah Waltman; [2023]
    Nyckelord :;

    Sammanfattning : AbstractMaxwell’s laws state that the divergence of a magnetic field always remains zero. In thecontinuous setting this is true for the magnetohydrodynamics equations. However, in thediscrete setting, the solution does not always remain divergence-free. LÄS MER

  4. 3. Utveckling och utvärdering av en funktionssäker pulsgivare : Konkretisering och vidareutveckling av en patenterad lösning vilken ämnas detektera låsta lager

    Master-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Kim Bojnell; [2023]
    Nyckelord :Pulsgivare; Mekanisk konstruktion; Driftsäkerhet; Funktionssäkerhet; Tillståndsövervakning; Feleffektanalys; Underhåll; Produktutveckling;

    Sammanfattning : An emerging industrial automation has led to higher demands required for construction of encoders to ensure functionality of automated processes. The main purpose of the encoder is to provide data which indicates the condition of a drive system. LÄS MER

  5. 4. Interaction for flexural column buckling : Analytical procedures compared with FE-simulations

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Noah Norberg; [2023]
    Nyckelord :;

    Sammanfattning : This master's thesis presents a study on the stability of steel structures under flexural bucklingconstraints. The study focuses on the interaction and behaviour of flexural buckling formulas in SSEN-1993-1-1 and Swedish BSK and the performance of actual structural members subjected to suchconstraints.

  7. 5. Simulations of a self-stabilizing fully submerged hydrofoil

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Henry Jacobson; [2023]
    Nyckelord :Hydrofoil; Self-Stabilizing; Lifting Line Theory; Fluid Mechanics; Numerical Methods; Backward Differentiation Formula; Fully Submerged Hydrofoil; Bärplan; bärplansbåt; självstabiliserande; lyftande linjeteori; strömningsme- kanik; numeriska metoder; Backward Differentiation Formula; fullt nedsänkt bärplan;

    Sammanfattning : Two models of a self-stabilizing hydrofoil system is developed where the effects from the struts and hydrofoil give torques for angular rotations. Lifting line theory for the hydrofoil which can twist is used. Nonlinear versions of the models are also developed and compared to find that the linear models use valid approximations. LÄS MER
