  2. 1. Measurement of azimuthal asymmetries in the hadronic final-state of deep inelastic scattering at HERA

    Author : Magnus Lindström; Partikel- och kärnfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; jets; DIS; azimuthal asymmetries; structure function; unfold; quantum field theory; Elementary particle physics; Elementarpartikelfysik; kvantfältteori; Physics; Fysik; Fysicumarkivet A:2000:Lindström;

    Abstract : Azimuthal asymmetries of the hadronic final state in deep inelastic scattering at HERA provide the opportunity to study the helicity of the interacting particles. We present a theoretical overview of the origin of these effects up to leading order in the strong coupling constant, $alpha_s$. READ MORE

  4. 2. Wind-turbine wakes - Effects of yaw, shear and turbine interaction

    Author : Elektra Kleusberg; Dan Henningson; Philipp Schlatter; Stefan Ivanell; Johan Meyers; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; wind-turbine wakes; yaw; tip-vortex breakdown; shear; computational fluid dynamics; actuator-line method; spectral-element method; Vindturbinsvakar; girning; turbulent nedbrott hos spetsvirvlar; skjuvning; vakinteraktion; beräkningsströmningsdynamik; actuator line-metod; spektralelementmetod; Engineering Mechanics; Teknisk mekanik;

    Abstract : The actuator-line method is used together with the incompressible Navier–Stokes equations to investigate the flow development behind wind turbines. Initial investigations focus on providing a thorough validation of the implementation in the spectral-element flow solver Nek5000 against existing numerical and experimental datasets. READ MORE
