  1. 11. Throughflow Study on Bleeding for Part Load Compressor Operation

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

    Författare :Simon Hedkvist; [2019]
    Nyckelord :Compressor; Minimum environmental load; Aerodynamic; Throughflow; Stability; Bleeding;

    Sammanfattning : The transition of the European energy grid to renewable energy sources is increasing the demand for back-up capacity with high flexibility. Current fossil fuel plants are continuously being forced into part load operation, where they are limited by pollution regulations that dictate their minimum environmental load, MEL. LÄS MER

  3. 12. Fatigue Analysis of a Lively Footbridge

    Master-uppsats, KTH/Bro- och stålbyggnad

    Författare :Kristi Bila; [2019]
    Nyckelord :;

    Sammanfattning : The commitment of building aesthetic bridges made of stiff materials results in theconstruction of slender structures highly susceptible to dynamic loading. In the caseof footbridges located over a highly trafficked highway, such dynamic loads maybe the aerodynamic pressure induced by the heavy trucks passing underneath thestructure and the pedestrian loading involving a pedestrian running and jumping.

  4. 13. Validation of a vortex panel method for aerodynamics and aero-elasticity of Wind Turbine

    Master-uppsats, KTH/Kraft- och värmeteknologi

    Författare :Antoine Thibierge; [2018]
    Nyckelord :;

    Sammanfattning : Ardema3D is a new type of vortex free model code that can simulate wind turbines. This code has been developed in order to replace the state of the art model, the blade element momentum (BEM). LÄS MER

  5. 14. Aerodynamics of Sailing Yachts : Force, Pressure and sail shape measurements as bridge between experiments and numerical simulations

    Master-uppsats, KTH/Marina system

    Författare :Francesco Giacobone; [2017]
    Nyckelord :;

    Sammanfattning : The present work reports the first systematic results obtained in wind tunnel and at full scale with theexperimental apparatus developed within the joint project among Politecnico di Milano, North Sails andCSEM. The steady state upwind aerodynamics of sailing yachts are investigated through the contemporarymeasurement of global forces, distributed pressures and sail flying shapes, and with numerical simulationsbased on Potential Theory and Navier-Stokes equations.

  7. 15. Topology Optimization as a Conceptual Tool for Designing New Airframes

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Torstensson Joakim; [2016]
    Nyckelord :Topology Optimization; Inertia Relief;

    Sammanfattning : During the two last decades, topology optimization has grown to be an accepted and used method to produce conceptual designs. Topology optimization is traditionally carried out on a component level, but in this project, the possibility to apply it to airframe design on a full scale aeroplane model is evaluated. LÄS MER
