  1. 1. Turbo For Fuel Cell Electric Vehicle

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Adam Hansson; Mohammed Abu Al-Soud; [2022]
    Nyckelord :Turbo; Fuel Cell; Centrifugal Compressor; Radial Turbine; Axial Turbine; Technology and Engineering;

    Sammanfattning : Turbo systems have long been implemented into vehicles to increase the specific power. Increasing the pressure for conventional vehicles decreases the mass of the engine and increases the efficiency. Conventional vehicles do however produce carbon dioxide emissions which have become an increasing issue that needs a solution. LÄS MER

  3. 2. Performance analysis of a small-scalewind turbine at variable pitch and withpitch unbalance

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Francesco Mazzeo; [2021]
    Nyckelord :Wind energy; wind turbine; pitch angle; pitch unbalance; Blade Element Momentum BEM theory; Computational Fluid Dynamics CFD ; wind tunnel experiments; oscillations;

    Sammanfattning : When it comes to design a wind turbine rotor, several parameters have to be taken into account. The present work focuses on the inclination of the blades with respect to the rotor plane, namely the pich angle. LÄS MER

  4. 3. Aerodynamic Design in Axial Turbine for Heavy Duty Applications

    Master-uppsats, Lunds universitet/Institutionen för energivetenskaper

    Författare :Eric Lennman; [2020]
    Nyckelord :Turbine design; MULTALL; Design methodology; Electric turbo compound turbine; Technology and Engineering;

    Sammanfattning : Turbomachinery design is based on multiple physical thermodynamical relations and fluid mechanics. Software implementing these relations in computing fluid flows have been broadly accessible since the 1990’s and has also become more applied to turbomachinery design. LÄS MER

  5. 4. 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

  7. 5. Thermal Loads in Space Turbines

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Emily Chen; [2019]
    Nyckelord :;

    Sammanfattning : Prediction of thermal loads within cavities in space turbine, has as been a challenging task  in aspects of achieving accurate and reasonable estimations that are crucial for design concepts. The difficulty lies within the turbulent flow and its thermal interaction with the structure inside such section. LÄS MER
