  1. 1. Fibre flow mechanisms

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

    Sammanfattning : 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. LÄS MER

  3. 2. Mitigating Microplastics Pollution in Urban Water Systems : Flow, actors, and control measures

    Författare :Emma Fältström; Stefan Anderberg; Annica Carlsson; Hamse Kjerstadius; Lian Lundy; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Municipalities; Plastic; Pollutants; Preventive measures; Stormwater; Wastewater; Water treatment;

    Sammanfattning : Water pollution has long been considered a challenge in urban areas. Urban wastewater and stormwater act as transport pathways for pollutants from urban areas to receiving waters. Microplastics are a pollution problem of growing concern. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  5. 4. Numerical simulation of plastic localization

    Författare :Ragnar Larsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-associated plastic flow; non-uniqueness; bifurcation; remeshing; strain-softening; adaptivity; Plasticity;

    Sammanfattning : .... LÄS MER

  7. 5. Blood Flow Dynamics in Burns

    Författare :Robin Mirdell; Erik Tesselaar; Simon Farnebo; Folke Sjöberg; Paul Van Zuijlen; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Objectives:Burns of intermediate thickness are hard to evaluate clinically. This often leads to unnecessary delays of up to 14 days before a surgical decision can be made. To counter this, several objective methods have been developed to determine the healing potential of the wound. LÄS MER
