  1. 1. Capillarity and wetting of non-Newtonian droplets

    University dissertation from KTH Royal Institute of Technology

    Author : Yuli Wang; Gustav Amberg; Daniel Bonn; [2016]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Dynamic wetting; contact line; diffusive interface; viscoelasticity; non-Newtonian; microfluidics; droplet impact; droplet spreading; Teknisk mekanik; Engineering Mechanics;

    Abstract : Capillarity and dynamic wetting of non-Newtonian fluids are important in many natural and industrial processes, examples cover from a daily phenomenon as splashing of a cup of yogurt to advanced technologies such as additive manufacturing. The applicable non-Newtonian fluids are usually viscoelastic compounds of polymers and solvents. READ MORE

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

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Stevin van Wyk; Laszlo Fuchs; Staffan Lundström; [2013]
    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

  3. 3. Computational studies of flow in Couette Rheometer and particle interaction in non-Newtonian fluids

    University dissertation from Lund University (Media-Tryck)

    Author : Naser Hamedi; [2016]
    Keywords : Non-Newtonian fluids; Correction factor; Fluid properties; Couette Rheometer; Particle interaction; Sedimentation; Computational Fluid dynamics; Plug flow; Herschel Bulkley; Power-law fluid; Immeresed boundary method;

    Abstract : This work aims to study the flow of non-Newtonian fluids and has two main goals. First, the power-law and Herschel Bulkley fluids are studied in a Couette rheometer. Second, the static and dynamic interaction of dual particles in power-law fluid are investigated. READ MORE

  4. 4. Experimental studies of large particles in Newtonian and non-Newtonian fluids

    University dissertation from KTH Royal Institute of Technology

    Author : Sagar Zade; Luca Brandt; Fredrik Lundell; Ellen Longmire; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; turbulence; finite-size; particle-laden flows; duct flow; pipe flow; viscoelastic fluid; viscoplastic fluid; Teknisk mekanik; Engineering Mechanics;

    Abstract : In everyday human life, laminar flow is arguably an exception whereas turbulent flow is the norm. Yet, the former has been much better understood, naturally since laminar flow renders itself to treatment in a relatively easier fashion compared to turbulence with its chaotic dynamics across multiple scales in space and time.

  5. 5. Global stability analysis of complex fluids

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Iman Lashgari; Luca Brandt; Francois Gallaire; [2013]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; non-Newtonian flow; Carreau model; Oldroyd-B model; FENE-P model; modal analysis; nonmodal analysis; sensitivity analysis;

    Abstract : The main focus of this work is on the non-Newtonian effects on the inertial instabilities in shear flows. Both inelastic (Carreau) and elastic models (Oldroyd-B and FENE-P) have been employed to examine the main features of the non-Newtonian fluids; shear-thinning, shear-thickening and elasticity.
