  2. 21. Simulation of collective phenomena in microswimmer suspensions

    Author : Dora Bardfalvy; Fysikalisk kemi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Collective motion is ubiquitous in biological and synthetic systems across manylength- and timescales. On the macroscopic scale, examples include schools of fish, herds of sheep and flocks of birds. On the microscopic scale, bacteria, algae and synthetic self-propelled particles exhibit a range of collective phenomena. READ MORE

  4. 22. Near wall fibre orientation in flowing suspensions

    Author : Allan Carlsson; Daniel Söderberg; Fredrik Lundell; Helge I. Andersson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid mechanics; fibre orientation; shear flow; wall effect; fibre suspension; papermaking; Fluid mechanics; Strömningsmekanik;

    Abstract : This thesis deals with fibre orientation in wall-bounded shear flows. The primary application in mind is papermaking. The study is mainly experimental,but is complemented with theoretical considerations.The main part of the thesis concerns the orientation of slowly settlingfibres in a wall-bounded viscous shear flow.

  5. 23. Lactic acid bacteria fermentations in oat-based suspensions

    Author : Olof Mårtensson; Bioteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; beta-glucans; probiotics; prebiotics; bacterial survival; Food and drink technology; Livsmedelsteknik; oats; ropiness; lactic acid bacteria; ropy;

    Abstract : This thesis deals with the fermentation characteristics of lactic acid bacteria (LAB) in oat-based suspensions, with formulation work of fermented products based on oat and with nutritional studies of these products. Changes in structure in terms of viscosity and ropiness were studied when exopolysaccharide (EPS)-producing LAB strains, namely, Lactobacillus delbrueckii subsp. READ MORE

  6. 24. Numerical study of transport phenomena in particle suspensions

    Author : Mehdi Niazi Ardekani; Luca Brandt; Gianluca Iaccarino; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering Mechanics; Teknisk mekanik;

    Abstract : Suspensions of solid particles in a viscous liquid are of scientific and technological interest in a wide range of applications. Sediment transport in estuaries, blood flow in the human body, pyroclastic flows from volcanos and pulp fibers in papermaking are among the examples. READ MORE
