  2. 2. Fibre flow mechanisms

    University dissertation from Stockholm : KTH

    Author : Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; [2005]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; TECHNOLOGY Chemical engineering Chemical process and manufacturing engineering Cellulose and paper engineering; TEKNIKVETENSKAP Kemiteknik Kemisk process- och produktionsteknik Cellulosa- och pappersteknik;

    Abstract : 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. READ MORE

  4. 4. Needle Punching of Wet Cellulose Fibre Structure

    University dissertation from Stockholm : KTH

    Author : Maria Klingberg; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; out-of–plane; fibre orientation; needle punching; fibre network structure; paperboard; cellulose fibre;

    Abstract : Needle punching of cellulose fibre structures was studied, in order to explore the possibility for a new method for bonding to be used in the paperboard industry. The interest in such subject was based on the need for stronger fibre-to-fibre bonding in the thickness direction of paperboard. READ MORE

  5. 5. Network Disruption and Turbulence in Fibre Suspensions

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Sven Andersson; [1998]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transition; friction; refractive index matching; Laser Doppler Anemometry LDA ; boundary-layer; Computational Fluid Dynamics CFD ; medium consistency MC ; network strength; fluidisation; pulp; suspension; fibres;

    Abstract : The production of paper pulp involves the handling of large quantities of fibre suspensions. Today's call for energy efficiency and environmentally sound processes has led to the development of MC (Medium Consistency) technology. READ MORE
