  1. 1. An Experimental Study of Reynolds Stress Closures in Shear Free and Weakly Sheared Turbulence

    Author : Dag Aronson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulence modelling; dissipation measurements; Reynolds stress closures; isotropic turbulence; anisotropic dissipation rate tensor; hot-wire anemometry; wall proximity effects; pressure strain rate correlations;

    Abstract : The objective of this thesis work is to obtain data enabling evaluation of closure hypotheses used in the Reynolds stress transport (RST) equations. Special attention has been devoted to studies of flow fields with shear free and weakly sheared turbulence. READ MORE

  2. 2. Orientation of fibres in suspensions flowing over a solid surface

    Author : Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Staffan Toll; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

    Abstract : The orientation of fibres suspended in a viscous fluid, flowing over a solid surface, has been studied experimentally. A shear layer was generated, by letting the suspension flow down an inclined plate. READ MORE

  3. 3. Studies of Topological Superconductors via Defects

    Author : Oladunjoye Awoga; Annica Black-Schaffer; Pascal Simon; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : Defects from impurities, edges, junctions or domain walls have local detrimental effects on the superconducting state. Defects are also important in topological superconductors, and useful in studying the properties of the superconducting order parameter. READ MORE

  4. 4. Experimental study of bubble dynamics and transport

    Author : Gunilla Andrée; Strömningsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energiforskning; Energy research; Particle Streak Photography; Shadowgraph; Particle Image Velocimetry; Bubble dynamics; bubble transport;

    Abstract : The thesis concerns experimental studies of bubble motion and the transport of large particles and bubbles. Bubbly flows are encountered in many engineering applications where the bubbles play an important role for the mass transfer between the phases, e.g. in stirred reactors. READ MORE
