  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

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

    Master-uppsats, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

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

    Sammanfattning : 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. LÄS MER

  7. 5. Optimization of b-value Acquisition and Parameter Estimation of Intravoxel Incoherent Motion Measurements

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Ivan Rashid; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Radiotherapy is commonly used for cancer treatment, given to approximately half of all cancer patients in Sweden. Despite its widespread usage, there is currently no non-invasive and reliable imaging method that can identify regions of radiation resistance. LÄS MER
