  1. 11. Forced response numerical investigation of a transonic compressor rotor

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Mariana Pires Gonçalves Toco Dias; [2023]
    Nyckelord :Compressor; rotor; blisk; aeroelasticity; aerodynamic damping; CFD; transient; forced response;

    Sammanfattning : The present thesis discusses the forced response of a rotor’s bladed-disk when excited by the periodic force produced by a wake generator, or Inlet Guide Vane (IGV),with 8 equally-spaced blades. These components are part of an axial transonic compressor rig, moreover the Transonic Compressor Darmstadt 1 (TCD1), located at the Technical University of Darmstadt. LÄS MER

    Sammanfattning : Climate change is a critical global issue that continues to shape the way we understand and interact with the world around us. It is discussed more than ever before, especially in politics. LÄS MER

  5. 14. Development of a DEM-FEM framework for infrastructure simulations

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Anita Ullrich; [2022-09-20]
    Nyckelord :;

    Sammanfattning : This thesis presents a coupling algorithm of the discrete element method (DEM) and finite element method (FEM). The algorithm formulates an explicit coupling of transient simulations of particle systems interacting with elastic bodies. LÄS MER

  7. 15. ANALYS AV HALVLEDARBRYTARE : SIMULERING, MÄTNING OCHBERÄKNING AVVÄRMEUTVECKLING OCH TRANSIENTER

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Erik Nilsson; [2022]
    Nyckelord :;

    Sammanfattning : BAE Systems Hägglunds are using contactors to control the power supply in their vehicle,but a replacer has been developed because the contactors take up a lot of space. The replacer is a self-designed semiconductor switch, which is called Ultra High Power DigitalOutPut or UHPDOP. LÄS MER
