  1. 1. Hydrodynamics of plane liquid jets aimed at applications in paper manufacturing

    Författare :Daniel Söderberg; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; liquid jet; transition; break-up; stability; wavelet; free surface; waves; streamwise streaks; fibre suspension; headbox; forming; shadowgraph; hot-film; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : Process industries are in general depending, in one way or the other, on fluid mechanics.Specifically, paper manufacturing, which probably is the dominant processindustry in Sweden, is depending on the flow of cellulose fibres suspended in water. LÄS MER

  3. 2. On Particle Transport and Turbulence Modification in Air-Particle Flows

    Författare :Camilla Ljus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; turbulent dispersion; hot film probe; turbulence measurements; turbulence modification; particle transport; two-fluid model;

    Sammanfattning : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. LÄS MER

  4. 3. Numerical Modelling of Some Engineering Heat Transfer Problems

    Författare :Daniel Eriksson; Värmeöverföring; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; Energiforskning;

    Sammanfattning : Engineering heat transfer problems are very often of a complex nature and most often no analytical solutions exist. One way to create solutions to such problems is to apply numerical methods. This study concerns heat transfer problems with coupled conduction, convection and thermal radiation. LÄS MER

  5. 4. Investigation of boundary layer transition for transonic flow over compressor and turbine airfoils

    Författare :Susanne Svensdotter; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis considers the laminar-turbulent transition overcompressor and turbine airfoils at high subsonic and transonicflow conditions.First, experiments on the laminar-turbulent transition on anisolated airfoil in high subsonic and transonic flow wereperformed. LÄS MER

  7. 5. Flow Measuring Techniques in Steady and Pulsating Compressible Flows

    Författare :Fredrik Laurantzon; Henrik Alfredsson; Björn Lindgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Flow measuring; compressible flow; steady flow; pulsating flow; hot-wire anemometry; cold-wire anemometry; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis deals with flow measuring techniques applied on steady and pulsatingflows. Specifically, it is focused on gas flows where density changes canbe significant, i.e. compressible flows. LÄS MER
