    Sammanfattning : Den svenska intensivvården drabbades 2020 av en svår kris när coronapandemin mångdubblade antalet svårt sjuka patienter i en redan hårt belastad verksamhet. För att hantera krisen behövde sjukvården ställa om till katastrofsjukvård. LÄS MER

  5. 4. Compressor Surge: Simulation, Modeling and Analysis

    Master-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Robin Massiquet; [2022]
    Nyckelord :Turbo compressor; Surge; Simulation; Modelling;

    Sammanfattning : The master thesis subject takes place in the automotive industry and specifically in the internal combustion engine area. The need of improving the efficiency of the engines leads to develop new technologies like turbo compressors. Some of the challenges to overcome are high rotational speed difficulties or extreme load and fatigue in the rotors. LÄS MER

  7. 5. FE Simulation of protective insulation of catalysts in exhaust after-treatment systems of trucks and buses : Investigation and characterization of catalytic converter support mat material for accurate modeling in finite element simulations

    Master-uppsats,
