  3. 2. Fibre flocculation during twin-wire roll forming

    Författare :Roger Bergström; KTH; []
    Nyckelord :;

    Sammanfattning : At the division of Paper Technology a forming unitconsisting of headbox, forming roll unit and reservoir systemfor suspension recirculation has been constructed, with themain purpose to experimentally study the paper forming event byvisually following the fibre flow phenomena in the formingzone.The effect of various running parameters upon the pressuredistribution, which is in correlation to the flow phenomenaoccuring during forming, has been studied with a flush mountedpressure sensor.

  4. 3. Fibre flow mechanisms

    Författare :Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; Cellulosa- och pappersteknik;

    Sammanfattning : The flow behaviour, and primarily the floc-floc interaction, of pulp paper suspensions have been studied visually. Analogy models based on these observations have been developed as well as the identification of important parameters of floc break-up in low shear rate flow fields. LÄS MER

    Sammanfattning : Yearly, 4,200 individuals in Sweden are diagnosed with lung cancer, of which 85 % are non-small cell lung cancer (NSCLC). The aims of this thesis were to investigate aspects of equality of care and outcomes in patients with NSCLC and to examine indicators of quality of life. LÄS MER
