  3. 2. Multiparticle Production in Strong Interactions

    Författare :Fredrik Söderberg; Centrum för miljö- och klimatvetenskap (CEC); []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Hadronisation; QCD; Bose-Einstein correlations; Elementary particle physics; Elementarpartikelfysik; quantum field theory; String fragmentation; kvantfältteori; Fysicumarkivet A:2003:Söderberg;

    Sammanfattning : An alternative formulation of the Lund fragmentation model for string states without gluons is presented. It is shown that the fragmentation process can be factorised into a product of transition operators with well-defined eigenfunctions and corresponding eigenvalues. LÄS MER

  4. 3. Variable Valve Actuation in a Spark Ignition Engine - A Flow Field and Heat Release Study

    Författare :Fredrik Söderberg; Förbränningsmotorer; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; framdrivningssystem; Gases; plasma; fluid dynamics; plasmas; Gaser; fluiddynamik; vakuumteknik; vibrationer; akustik; Motors and propulsion systems; Motorer; hydraulik; Maskinteknik; vibration and acoustic engineering; Laser Doppler Velocimetry Particle Image Velocimetry PIV LDV Wavelet Computational Fluid Dynamics CFD Variable Valve Actuation Timing Turbulence Combustion Engine Spark Ignition Miller; hydraulics; vacuum technology; Mechanical engineering;

    Sammanfattning : The objective of this thesis was to find ways of improving part-load efficiency for a spark ignition engine by studying the effects of variable-valve actuation on fluid flow and combustion. The in-cylinder flow was measured with laser doppler velocimetry, LDV, and particle image velocimetry, PIV. LÄS MER

  5. 4. An experimental study of fiber suspensions between counter-rotating discs

    Författare :Charlotte Ahlberg; Daniel Söderberg; Fredrik Lundell; Srdjan Sasic; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fiber suspension flow; rotating discs. shear flow; self-organization of fibers; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The behavior of fibers suspended in a flow between two counter-rotating discs has been studied experimentally. This is inspired by the refining process in the papermaking process where cellulose fibers are ground between discs in order to change performance in the papermaking process and/or qualities of the final paper product.

  7. 5. Near wall fibre orientation in flowing suspensions

    Författare :Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Helge I. Andersson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; wall effect; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : This thesis deals with fibre orientation in wall-bounded shear flows. The primary application in mind is papermaking. The study is mainly experimental,but is complemented with theoretical considerations.The main part of the thesis concerns the orientation of slowly settlingfibres in a wall-bounded viscous shear flow.
