  1. 1. Multiscale & Multiphysics Modelling of Thrust Pad (Air) Bearings

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Nipon Roy; [2023]
    Keywords : Finite element modelling; Air bearing; Multiphysics simulations; Air lubrication; surface texture; Topology optimization;

    Abstract : Without lubrication, machines are not imaginable to perform over a long period of time and complete their designated operations. With its omnipresent availability, the air is capable of functioning as a lubricant in long operations very efficiently. Moreover, thrust bearings support axial loads and transmit power at the same time under heavy loads. READ MORE

  3. 2. 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.

  4. 3. Design of cooling-air permeable coil support

    University essay from KTH/Hållfasthetslära

    Author : Rozbeh Ghassemi; [2023]
    Keywords : Topology optimization; FEM-simulations; CFD-simulations; Material selection; Topologioptimering; FEM-simuleringar; CFD-simuleringar; Materialval;

    Abstract : Coil supports are integral load-bearing components employed in generators andmotors. They serve the purpose of preventing excessive deformation and maintaininga stable position of the coils responsible for generating power and magnetic fieldswhen rotating. READ MORE

  5. 4. Study of mixing and exchange in a drinking water reservoir using CFD modeling

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Nadja Rabizadeh; [2023]
    Keywords : CFD; Fluid Mechanics; OpenFOAM; drinking water reservoir; URANS; transient; exchange of water; mixing; Norrvatten;

    Abstract : This thesis examines water mixing and exchange in a drinking water reservoir operated by themunicipal association Norrvatten. Recent water samples from the reservoir’s outgoing waterhave shown an increase in culturable bacteria during late summer and fall. READ MORE

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

    University essay from KTH/Teknisk mekanik

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

    Abstract : 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. READ MORE
