  2. 1. Network Disruption and Turbulence in Fibre Suspensions

    Author : Sven Andersson; Chalmers tekniska högskola; []
    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

  4. 2. Flow and Mixing of Pulp Suspensions

    Author : Johan Pettersson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; flow behaviour; boundary-layer; Medium Consistency MC ; mixing; yield stress; suspension; pulp; Laser Doppler Anemometry LDA ; turbulence; fibre;

    Abstract : When producing pulp and paper, pulp suspensions are treated in a number of unit operations at medium consistency (MC) concentrations (3-15% by weight). Pulp suspensions at these concentrations behave as solids at low shear rates, but at sufficiently high shear rates they start to flow and can even be made to act as water. READ MORE
