  1. 16. Growth and removal of inclusions during ladle refining

    Författare :Mats Söder; Pär Jönsson; Hae-Geon Lee; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meteorology; inclusions; steel; ladle; cluster growth; modelling; Meteorologi; Meteorology; Meteorologi;

    Sammanfattning : The overall purpose of this thesis work has been to further our understanding of the growth and removal of inclusions in gas- and induction-stirred ladles. The primary focus has been on alumina inclusions.Growth mechanisms were studied using data from fundamental mathematical models of gas- and induction-stirred ladles. LÄS MER

  3. 17. Experiments on biofilm formation and growth in laminar flows

    Författare :Cornelius Wittig; Shervin Bagheri; Thomas Crouzier; Wouter van der Wijngaart; Eleonora Secchi; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biofilm; streamers; wall shear stress; OCT; Teknisk mekanik; Engineering Mechanics;

    Sammanfattning : The interaction between fluid dynamics and biofilm growth plays a key role in both medical and industrial applications. Biofilms, or bacteria that are embedded in a protective matrix of extracellular polymeric substances, settle on interfaces such as on implanted devices or ship hulls. LÄS MER

  4. 18. The Dynamics of Firm and Industry Growth : The Swedish Computing and Communications Industry

    Författare :Dan Johansson; KTH; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; The experimentally organised economy; Competence blocs; Industrial Dynamics; Industrial Transformation; Firm age; Small-firm growth; Turnover of firms; Computing and Communications industry; IT industry; Institutions;

    Sammanfattning : The growth of the Swedish Computing and Communicationsindustry is studied in this thesis. Growth is seen as a dynamicprocess moved by the entry, expansion, contraction and exit offirms.The analysis is founded on the theory of the ExperimentallyOrganised Economy, which views the economy as an experimentalprocess.

  5. 19. Stability analysis and transition prediction of wall-bounded flows

    Författare :Ori Levin; KTH; []
    Nyckelord :Boundary layer; wall jet; algebraic growth; exponential growth; lift-up effect; streamwise streaks; Tollmien-Schlichting waves; free-stream turbulence; roughness element; transition prediction; Parabolized Stability Equations; Direct Numerical S;

    Sammanfattning : Disturbances introduced in wall-bounded .ows can grow andlead to transition from laminar to turbulent .ow. In order toreduce losses or enhance mixing in energy systems, afundamental understanding of the . LÄS MER

  7. 20. Drowning-out crystallisation of benzoic acid : Influence of processing conditions and solvent composition on crystal size and shape

    Författare :Xiomara Holmbäck; KTH; []
    Nyckelord :solvent effect; drowning-out; crystallization; benzoic acid; solubility; crystal habit; crystal growth; interfacial energy; growth mechanism;

    Sammanfattning : The aim of the present investigation is to increase theunderstanding of the role played by the solvent in inhibitingor enhancing crystal growth. Drowning-out crystallizationexperiments has been performed by the controlled addition ofwater or ethanol water mixtures to a saturated solution ofbenzoic acid in ethanol-water mixtures. LÄS MER
