  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. 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

  4. 3. The Collapse of Decoherence : Can Decoherence Theory Solve The Problems of Measurement?

    University essay from Uppsala universitet/Materialteori

    Author : Karl Herlin; [2023]
    Keywords : quantum mechanics; quantum physics; philosophy of physics; interpretation of quantum mechanics; measurement problem; problem of preferred basis; problem of non-observability of interference; problem of definite outcomes; environment induced superselection rules; copenhagen interpretation; decoherence; irreducibility of classical concepts;

    Abstract : In this review study, we ask ourselves if decoherence theory can solve the problems of measurement in quantum mechanics. After an introduction to decoherence theory, we present the problem of preferred basis, the problem of non-observability of interference and the problem of definite outcomes. READ MORE

  5. 4. Modelling the Water Table in a Bog

    University essay from Lunds universitet/Fysiska institutionen; Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Author : Tobias Bowley; [2023]
    Keywords : Physics and Astronomy;

    Abstract : Over the past five years, an ongoing study at INES, Lund University, have examined the encroachment of trees and vegetation into a bog ecosystem in northern Scania, Sweden. While several factors have been identified as contributing to this ecological transformation, including, nutrient availability, and climate, the hydrological aspect remains a key area of investigation.

  6. 5. Nature representation in forest fire management in Jämtland, Sweden

    University essay from SLU/Dept. of Urban and Rural Development

    Author : Swenja Dorn; [2023]
    Keywords : nature; representation; nature representation; forest fire management;

    Abstract : With a globally increasing mean temperature and drier summers in Europe, forest fires are becoming a wider known issue in the forest landscape. Having been part of the boreal forest landscape for millennia, their influence becomes more pronounced due to these changes. READ MORE
