  4. 3. Numerical Simulations of Cooling Concepts Related to Gas Turbine Combustors

    Författare :Andreas Abdon; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Motors and propulsion systems; plasma; combustor; gas turbine; cooling; numerical simulations; turbulence; ribs; impingement; Gases; fluid dynamics; plasmas; fluiddynamik; Gaser; Motorer; framdrivningssystem; Thermal engineering; applied thermodynamics; Termisk teknik; termodynamik;

    Sammanfattning : The mean by which a gas turbine combustor is cooled is of major importance for the efficiency and emission performance of the machine. The trends of increasing top cycle temperature and leaner combustion have also been accompanied by a need of efficient use of the cooling air. LÄS MER

  5. 4. Modeling of Magnetic Fields and Extended Objects for Localization Applications

    Författare :Niklas Wahlström; Fredrik Gustafsson; Thomas B. Schön; Simon Maskell; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Localization; magnetic tracking; extended target tracking; signal processing; machine learning; Gaussian processes; deep dynamical model; discretization;

    Sammanfattning : The level of automation in our society is ever increasing. Technologies like self-driving cars, virtual reality, and fully autonomous robots, which all were unimaginable a few decades ago, are realizable today, and will become standard consumer products in the future. LÄS MER

  7. 5. Active Control of Propeller-Induced Noise in Aircraft : Algorithms & Methods

    Författare :Sven Johansson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; active control of sound; active noise control; anc; actuator individual normalized filtered-x lms; filtered-x lms algorithm; newton algorithm; complex lms; multireference algorithm; leaky lms; control effort weighting; feedforward control; feedback contro;

    Sammanfattning : In the last decade acoustic noise has become more and more regarded as a problem. In cars, boats, trains and aircraft, low-frequency noise reduces comfort. Lightweight materials and more powerful engines are used in high-speed vehicles, resulting in a general increase in interior noise levels. LÄS MER
