  1. 1. Fibre flow mechanisms

    Author : Roger Bergström; Ulf Björkman; Bo Norman; Mark Martinez; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fibre flow; floc; shear; compression; fibre network; stress chain; Cellulose and paper engineering; 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

  2. 2. Inclusion Behaviour under a Swirl Flow in a Continuous Casting Process

    Author : Yang Ying; Pär Jönsson; Dong-Yuan Sheng; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; inclusion behaviour; swirl flow; rotating magnetic field; electromagnetic swirl flow generator; full type; half type; submerged entry no zzle; mold;

    Abstract : A swirl flow generated in a submerged entry nozzle (SEN) can effectively improve a flow pattern and heat transfer in a continuous casting process by using the methods of “swirl blade type” and “electromagnetic type”. In order to obtain a further in-depth understanding with respect to the effect of a swirl flow on a continuous casting process, the inclusion behaviour in a SEN and a mold was studied in the present work.

  3. 3. Flow and Compression of Granulated Powders : The Accuracy of Discrete Element Simulations and Assessment of Tablet Microstructure

    Author : Ann-Sofie Persson; Göran Frenning; Göran Alderborn; Marie Wahlgren; Uppsala universitet; []
    Keywords : MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Discrete Element Method; Granule; Flow; Angle of Repose; Discharge Rate; Shear; Rolling friction; Compression; Elastic deformation; Microstructure; Degree of compression; Tensile strength; Galenisk farmaci; Pharmaceutics;

    Abstract : Simulations are powerful and important tools for gaining insight into powder processes. Ultimately, simulations have the potential to replace experiments. Thus, accurate models and insight into the essential factors for descriptions of powder behaviour are required. READ MORE

  5. 5. Modelling of Bingham Suspensional Flow : Influence of Viscosity and Particle Properties Applicable to Cementitious Materials

    Author : Annika Gram; Björn Lagerblad; Ulrich Diederichs; KTH; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Self-Compacting Concrete; SCC; Fresh concrete flow; Numerical simulation; Viscosity; Open channel flow;

    Abstract : Simulation of fresh concrete flow has spurged with the advent of Self-Compacting Concrete, SCC. The fresh concrete rheology must be compatible with the reinforced formwork geometry to ensure complete and reliable form filling with smooth concrete surfaces. READ MORE
