  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. Numerical Study on Acoustic Phenomena in Cavities for Aero-engine Applications

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Eglantin Gjoni; [2023]
    Keywords : ;

    Abstract : For about seventy years, noise generated by grazing flow past a cavity has been thoroughly studied. Yet, a coherent theory that describes such phenomena is missing. Lately, this phenomena started to be investigated in bleeding systems of aero-engines. READ MORE

  4. 3. Simulation of Combustion in a Hybrid Rocket Engine

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Oscar Andersson; [2023]
    Keywords : Thesis; Hybrid Rocket Engine; CFD; computational fluid dynamics; combustion;

    Abstract : A numerical investigation on the combustion mechanics of a hybrid rocket engine is performed through unsteady Reynolds-averaged Navier-Stokes simulation. The hybrid rocket engine model is based on an experimental laboratory scale engine design operating on GOX and HDPE as a propellant. READ MORE

  5. 4. Forced response numerical investigation of a transonic compressor rotor

    University essay from KTH/Skolan för industriell teknik och management (ITM)

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

    Abstract : 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. READ MORE

  6. 5. Method development for the use of Smoothed-particle hydrodynamics simulations for vehicle soiling analysis

    University essay from Linköpings universitet/Mekanisk värmeteori och strömningslära

    Author : Josep Plana Riu; [2022]
    Keywords : ;

    Abstract : An increasing amount of sensors is being placed in cars in order to monitor their vicinities, which performance is highly dependant on the driving conditions, in which weather has a big role, and thus water contamination is a topic that will increase its importance in the future of the car industry. One of these sources of contamination is self-soiling: how cars get dirty because of their own tires. READ MORE
