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

    University essay from KTH/Skolan för teknikvetenskap (SCI)

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

    Abstract : 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. READ MORE

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

    University essay from Uppsala universitet/Institutionen för informationsteknologi

    Author : Erik Björklund; Peter Mårtensson; Noah Waltman; [2023]
    Keywords : ;

    Abstract : 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. READ MORE

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

    University essay from KTH/Bro- och stålbyggnad

    Author : Noah Norberg; [2023]
    Keywords : ;

    Abstract : 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.

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

    University essay from KTH/Matematik (Avd.)

    Author : Henry Jacobson; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 5. Virtual Sensing for Cluster Vacuum Control

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Carl Egenäs; Axel Sacilotto; [2023]
    Keywords : ;

    Abstract : The purpose of this project was to develop a virtual sensing model in order to estimate the vacuum level in the milking cluster with data collected further along the milk tube. Measuring the cluster vacuum level is desirable for many applications, such as control and monitoring, but due to the cow's tendency to kick, chew and stomp on anything within reach, placing a sensor in or close to the cluster is both difficult and impractical.
