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

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Josep Plana Riu; [2022]
    Nyckelord :;

    Sammanfattning : 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. LÄS MER

  3. 2. Numerical evaluation of the ground vortex

    Master-uppsats, KTH/Teknisk mekanik

    Författare :Martin Babo; [2022]
    Nyckelord :Turbofan engine; CFD; Flow simulation; Ground Vortex; External aerodynamics;

    Sammanfattning : This master thesis covers the realization of a CFD calibration study regarding the numerical simulation of the ground vortex phenomenon. As part of InVIGO project (EU CleanSky2), wind tunnel test campaigns were performed using a nacelle model combined with a movable raised floor. LÄS MER

  4. 3. CFD-Method for 3D Aerodynamic Adjoint Simulations : For External Automotive Aerodynamics

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Marcus Lång; [2019]
    Nyckelord :;

    Sammanfattning : Today’s rules and regulations regarding emissions from combustion vehicles are very strict and the travel range per tank and/or charge, especially for electric vehicles, is a crucial factor which will always be considered by the customers. Hence, automotive manufacturers strive to boost fuel and battery economy. LÄS MER

    Sammanfattning : This is a master thesis report in vehicle aerodynamics and cooling air management. The thesis is carried out at China Euro Vehicle Technology (CEVT) AB and is part of the course P7010T, Master Thesis in Space Engineering at Luleå University of Technology (LTU). LÄS MER

  7. 5. Transonic Flutter for aGeneric Fighter Configuration

    Master-uppsats, KTH/Flygdynamik

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

    Sammanfattning : 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.
