  1. 1. On the Fluid Mechanics of Partial Dewatering during Roll Forming in Paper Making

    Författare :Richard Holm; KTH; []
    Nyckelord :Fluid mechanics; roll forming; partial dewatering; capillary waves;

    Sammanfattning : The present work deals with some aspects of the fluidmechanics of paper-making,more specifically partial dewateringduring roll forming. The study is mainly experimental. Pressureand wire position measurements have been carried out in anexperimental facility, the KTH-Former,which models the rollforming zone of a paper machine. LÄS MER

  3. 2. Fluid mechanics of fibre suspensions related to papermaking

    Författare :Richard Holm; Gustav Amberg; R. Krekes; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Applied mechanics; applied fluid mechanics; fibre suspensions; roll-forming; sedimentation; shear flow; Teknisk mekanik; Engineering mechanics; Teknisk mekanik;

    Sammanfattning : This thesis deals with fluid dynamic mechanisms related to papermaking, specif- ically: the initial dewatering mechanisms during roll-forming and fibre motion in sedimentation and in shear flow. Pressure and wire position measurements have been conducted in a model resembling the forming zone and the measured pressure distributions are shown to have more complex patterns than the simple model p / T/R (where T is the wire tension and R is the roll radius).
