  1. 1. Modeling and simulation of paper structure development

    University dissertation from Sweden : Mid Sweden University

    Author : Stefan B Lindström; [2008]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forming; Fibre; Paper; Fibre suspension; Paper structure; Simulation; Rheology;

    Abstract : A numerical tool has been developed for particle-level simulations of fibre suspension flows, particularly forming of the fibre network structure of paper sheets in the paper machine. The model considers inert fibres of various equilibrium shapes, and finite stiffness, interacting with each other through normal, frictional, and lubrication forces, and with the surrounding fluid medium through hydrodynamic forces.

  4. 4. Infrared Emittance of Paper Method Development, Measurements and Application

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Caroline Hyll; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Emittance; Emissivity; Thermography; Paper; Sheet; Papermaking; Paper mechanics; Moisture; Material properties; Reflectance; Transmittance; Absorptance; Infrared; Mid-wavelength infrared; MWIR; Long-wavelength infrared; LWIR; Angle-resolved; Directional;

    Abstract : Thermography is a non-destructive technique which uses infrared radiation to obtain the temperature distribution of an object. The technique is increasingly used in the pulp and paper industry. To convert the detected infrared radiation to a temperature, the emittance of the material must be known. READ MORE

  5. 5. Protein structure prediction Zinc-binding sites, one-dimensional structure and remote homology
