  2. 11. Blood Flow variations in Large Arteries due to non-Newtonian rheology

    Author : Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blood; Rheology; Viscosity; non-Newtonian; CFD; Bifurcations; Unsteadiness; Wall Shear Stress; Atherosclerosis;

    Abstract : The blood is a complex fluid that contains, in addition to water, cells, macro-molecules and a large number of smaller molecules. The physical properties of the blood are therefore the result of non-linear interactions of its constituents, which are influenced by the local flow field conditions. READ MORE

  4. 12. Heat transfer in falling film evaporation of black liquor - Experiments and theory

    Author : Miriam Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; evaporator; black liquor; falling film; kraft pulp mill; Heat transfer; evaporation; viscosity; correlations; experimental; non-Newtonian;

    Abstract : Pulp and paper industry uses a large part of the total amount of energy in industry in Sweden. The evaporation plant has the major energy demand in the kraft pulp mill, which is the dominant type of chemical pulp mill. Previous studies have shown potential to decrease the live steam demand for the pulp process, e.g. READ MORE

  5. 13. Effects of Processing on Dietary Fibre in Vegetables

    Author : Maria Svanberg; Avdelningen för livsmedel och läkemedel; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; low molecular weight carbohydrates; carrot cultivars; molecular weight distribution; viscosity; water-soluble polysaccharides; processing; Dietary fibre; vegetables; bulking capacity; rats; Food and drink technology; Livsmedelsteknik;

    Abstract : Several beneficial effects have been connected with dietary fibre. Insoluble fibre has a good faecal bulking capacity, whereas soluble and viscous dietary fibre has been shown to have beneficial effects on carbohydrate and lipid metabolism. READ MORE

  6. 14. Single Phase Convective Heat Transfer with Nanofluids : An Experimental Approach

    Author : Ehsan Bitaraf Hgahighi; Björn E. Palm; Elena V. Timofeeva; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nanofluid; convective heat transfer; thermal conductivity; viscosity; heat transfer coefficient; performance; pumping power; Reynolds number; shelf stability;

    Abstract : Nanofluids (NFs) are engineered colloids of nanoparticles (NPs) dispersed homogenously within base fluids (BFs). Due to the presence of NPs, the thermophysical and transport properties of BFs are subject to change. READ MORE

  7. 15. On particles and slags in steel casting

    Author : Dimitrios Siafakas; Anders E.W. Jarfors; Taishi Matsushita; Sridhar Seetharaman; Jönköping University; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hadfield steel; deoxidation; grain size; inoculation; particles; viscosity; slag;

    Abstract : Hadfield steel is widely accepted as one of the most important steel alloys utilized in industrial applications where high impact strength and wear resistance is required. Like in most metallic alloys used for component casting, the mechanical properties of Hadfield steel are directly connected with the microstructure of the material. READ MORE
