  1. 1. Computational Fluid Dynamics and Modeling of a Free Surface Flow

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Mathieu Marmier; [2023]
    Keywords : CFD; Free Surface Flow; VOF; STAR-CCM ; Multiphase Simulation; Nuclear Engineering; Fluid Mechanics;

    Abstract : 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. READ MORE

  3. 2. Modelling development of ECMO return flow in bifurcating arteries

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Friederike Schäfer; [2021]
    Keywords : Fluid Mechanics; CFD; ECMO;

    Abstract : 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. READ MORE

  4. 3. A Topology-Based Method for Inferring Turbulence in Unsteady Flows

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Tobias Edwards; [2021]
    Keywords : ;

    Abstract : Understanding the rise and evolution of turbulence is an important component of designing vehicles and turbomachinery that both have long life and are efficient. To this end, researchers study the complex phenomenon of turbulence. READ MORE

  5. 4. Numerical modelling of cold helium safety discharges from the cryogenic distribution line

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Jonathan Persson; [2020]
    Keywords : Technology and Engineering;

    Abstract : The European Spallation Source, ESS, is a project currently with 17 Partner Countries, and with Sweden and Denmark as host nations. The ESS main facility is being constructed in Lund, to ultimately become the world’s most powerful neutron source, providing around 30 times brighter neutron beams than any earlier facility.

  6. 5. Transonic Flutter for aGeneric Fighter Configuration

    University essay from KTH/Flygdynamik

    Author : Axel Bååthe; [2018]
    Keywords : Flutter; Aeroelasticity; Transonic; Unsteady Aerodynamics; Doublet-Lattice Method; Full-Potential Equation; PK-Method;

    Abstract : A hazardous and not fully understood aeroelastic phenomenon is the transonic dip,the decrease in flutter dynamic pressure that occurs for most aircraft configurationsin transonic flows. The difficulty of predicting this phenomenon forces aircraft manufacturersto run long and costly flight test campaigns to demonstrate flutter-free behaviourof their aircraft at transonic Mach numbers.
