  1. 16. Aeroelastic Analysis of a Morphing Wing for Airborne Wind Energy Applications

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Johannes Hall; [2017]
    Nyckelord :airborne wind energy; fluid structure interaction; gust wind modelling; Technology and Engineering;

    Sammanfattning : The aim of this thesis is to set up a high-fidelity fluid structure interaction (FSI) simulation environment to study the gust load alleviation capability of camber-morphing airborne wind energy (AWE) wings. The simulation environment will enable studying the transient flow phenomena around the wing when encountering wind gusts and gives the possibility of investigating dynamic instabilities. LÄS MER

  3. 18. Numerical Investigations of a Partitioned FSI Algorithm for Tetra Pak's Filling Tube

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Leo Andersson; [2016]
    Nyckelord :fluid-structure interaction; FSI; added mass effect; partitioned implicit scheme; stability; Rayleigh damping; grid flux under-relaxation; Technology and Engineering;

    Sammanfattning : Numerical simulations of fluid-structure interaction of a water-filled tube with a free surface are conducted using an implicit partitioned coupling scheme. Abaqus and STAR-CCM+ are used for the solid- and fluid domains respectively. This application has stability issues, with the most severe turning out to be the added mass effect. LÄS MER

  4. 19. Added Properties in Kaplan Turbine - a preliminary investigation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Stina Bergström; [2016]
    Nyckelord :Added mass; added damping; fluid-solid interaction; acoustic coupled simulation; two way coupled simulation;

    Sammanfattning : A preliminary investigation of the added properties called added mass, added damping and added stiffness have been performed for a Kaplan turbine. The magnitude of dimensionless numbers have been used in order to classify the interaction of the fluid and the solid. LÄS MER

  5. 20. A CFD Method for Simulation of Gas-Liquid Flow in Cooling Systems : An Eulerian-Eulerian Approach

    Master-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Malin Lind; Karl Johan Josefsson; [2016]
    Nyckelord :CFD; Gas-Liquid; Two-phase; Eulerian; Air bubbles; Flow; Eulerian-Eulerian; Cooling system;

    Sammanfattning : When designing modern engines it is important to construct a cooling system that cools the engine structure efficiently. Within the cooling system there is always a certain amount of air which can accumulate and form air pockets in critical areas, such as the water jacket, which can lead to wall degradation. LÄS MER
