  1. 1. Modelling development of ECMO return flow in bifurcating arteries

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Friederike Schäfer; [2021]
    Nyckelord :Fluid Mechanics; CFD; ECMO;

    Sammanfattning : Veno-arterial extracorporeal membrane oxygenation (V-A ECMO) is a life saving therapy for critically ill patients experiencing a heart and lung failure. During this therapy, a common complication is limb ischemia in the leg where the return cannula reintroduces the oxygenated blood to the patient. LÄS MER

  3. 2. CFD simulation of dip-lubricated single-stage gearboxes through coupling of multiphase flow and multiple body dynamics : an initial investigation

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Nasir Imtiaz; [2018]
    Nyckelord :transmissions; churning losses; CFD; STAR-CCM ; FZG gearbox; planetary gearbox; RBM; MRF; unsteady framework; VOF; immiscible; overset meshing technique;

    Sammanfattning : Transmissions are an essential part of a vehicle powertrain. An optimally designed powertrain can result in energy savings, reduced environmental impact and increased comfort and reliability. Along with other components of the powertrain, efficiency is also a major concern in the design of transmissions. LÄS MER

  4. 3. ON SIMULATING COMPRESSIBLE FLOWS WITH A DENSITY BASED SOLVER

    Master-uppsats, KTH/Mekanik

    Författare :Sathyanarayanan Chandramouli; [2016]
    Nyckelord :Coupled density based solver; High Pressure Turbine Nozzle Guide Vane;

    Sammanfattning : A coupled density based solver in the framework of foam-extend is used to perform simulations of transonic flows. The solver is based on an explicit and time-accurate algorithm and is coupled to a compressible Unsteady Reynolds-Averaged Navier-Stokes (URANS) and a Large Eddy Simulation (LES) module. LÄS MER
