  1. 1. Flow and Rheology of Pulp Suspensions at Medium Consistency

    Author : Tomas Wikström; Chalmers University of Technology; []
    Keywords : fluidisation; yield stress; agitation; pulp suspension; computational fluid dynamics; fibre properties; turbulence; screening; Bingham model;

    Abstract : Traditionally, development of pulp processing equipment has been based on the accumulation of qualitative knowledge (experience) with respect to the interaction of equipment and pulp suspensions. This way of developing equipment requires several trials and prototypes before the final product and process data can be established. READ MORE

  2. 2. Network Disruption and Turbulence in Fibre Suspensions

    Author : Sven Andersson; Chalmers University of Technology; []
    Keywords : 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

  3. 3. Particle Coating in a Wurster Type Bed

    Author : Stina Karlsson; Chalmers University of Technology; []
    Keywords : TEKNIK OCH TEKNOLOGIER; MEDICIN OCH HÄLSOVETENSKAP; ENGINEERING AND TECHNOLOGY; MEDICAL AND HEALTH SCIENCES; Drying; Particle; Tracking technique; Spouted bed; Fluidisation; Multiphase flow; CFD; Trajectory; Coating; Wurster;

    Abstract : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. READ MORE

    Author : Stina Karlsson; Chalmers University of Technology; []
    Keywords : coating; drying; spouted bed; fluidisation; single particle; Wurster; tracking technique; trajectory;

    Abstract : .... READ MORE

  5. 5. Dynamics of wood particle pyrolysis applied to gas-solids fluidisation

    Author : Ulf Sand; Rebei Bel Fdhila; Lucien Masbernat; Mälardalens högskola; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Environmental engineering; Miljöteknik; Energi- och miljöteknik;

    Abstract : Avhandlingen behandlar matematiska modellerings- och simuleringsaspekter samt resultat rörande pyrolys av stora och små träpartiklar. Avhandlingsarbetet är inriktat på två specifika processer. Den ena är pyrolys av enstaka träpartiklar och den andra är pyrolys av fluidiserade träpartiklar. READ MORE
