  1. 1. Cable Shape Optimization - Drag Reduction of Cables Used in Marine Applications

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Simon Garpenquist; [2023]
    Nyckelord :Wind Tunnel Experiment; Computational Fluid Dynamics; Aerodynamic Forces; Drag Reduction; Shape Optimization; Flow around Cylinders; Yacht Racing;

    Sammanfattning : It is important to understand the aerodynamic properties of tensioned cables (e.g. used in suspension bridges and yacht riggings), both for drag reduction and vibrational suppression purposes. LÄS MER

  3. 2. A coupling method using CFD, radiative models and a surface model to simulate the micro-climate

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Joseph Vernier; [2023]
    Nyckelord :Computational Fluid Dynamics; Fluid Mechanics; Numerics; Micro-climate modeling; Radiation; Crop modeling; Photovoltaic panels;

    Sammanfattning : The increasing demand for energy, depletion of fossil fuels, rising global warming, and greenhouse gas emissions have stimulated the need for widespread development and adoption of renewable energy sources (RES) worldwide. Among these sources, solar energy has emerged as a major contender to meet the growing demand. LÄS MER

  4. 3. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Johanna Adbo; [2023]
    Nyckelord :QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

    Sammanfattning : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. LÄS MER

  5. 4. Thermal Analysis of Tap- Changers

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Daniel Lundberg; [2023]
    Nyckelord :Thermal analysis; COMSOL; tap-changers; heat transfer;

    Sammanfattning : This thesis provides a way of mapping the temperature development of the tap-changer oil for some different standardized loading cases. The project was in collaboration with Hitachi Energy for one of their production cites situated in Ludvika, Sweden. The software used for the simulation environment was COMSOL 6.1 which is a finite element solver. LÄS MER

  7. 5. Product Line Optimization of Force Transducers : Replacing R87 with R03 in Strip Tension Systems

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad mekanik

    Författare :Pedram Esmailzadeh Anari; [2023]
    Nyckelord :Force Transducers; Load Cells; Magnetoelasticity; Pressductor; Strip Tension Systems; Mechanical Simulations; Thermal Simulations; Prototype Testing;

    Sammanfattning : The aim of this thesis is to investigate the potential of replacing the material 1.4418 (R87), currently used in ABB's PFCL201 load cells, with the material 1.402 (R03). LÄS MER
