  2. 11. Water-based hydraulic fluids : rheology and elastohydrodynamic lubrication

    Author : Ove Isaksson; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design; Maskinelement; Machine Elements;

    Abstract : Experiments have been carried out to measure traction, antiwear and rheological properties of water-based hydraulic fluids. Four types of fluids have been examined, emulsions, micro-emulsions, synthetic solutions and water-glycols. READ MORE

  4. 12. A Lagrangian-Eulerian simulation framework for viscoelastic fluid flows

    Author : Simon Ingelsten; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Computational Fluid Dynamics; non-Newtonian flow; Immersed boundary methods;

    Abstract : Viscoelastic fluids appear in various industrial applications, including adhesive application, additive manufacturing, seam sealing and parts assembly with adhesive. These processes are characterized by complex geometry, moving objects and transient multiphase flow, making them inherently difficult to simulate numerically. READ MORE

  5. 13. Evaluation of a Measuring System for Determining Extensional Properties

    Author : Magda Nyström; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LPTT-model; Viscoelastic fluid; Boger fluid; numerical simulation; FENE-CR model; extensional rheology; White-Metzner model; hyperbolic contraction flow;

    Abstract : Effective and reliable characterisations of fluids are important to gain knowledge of thebehaviour and to govern the properties of a fluid. Since food products often are non-Newtonian, viscoelastic liquids, the characterisation becomes more complicated. READ MORE

  6. 14. Transporting highly concentrated slurries with centrifugal pumps : the thickened minerals tailings example

    Author : Thord Wennberg; Magnus Fahlgren; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineralteknik; Mineral Processing;

    Abstract : New technologies are continuously considered for the handling and deposition of tailings. With thickened tailings only a fraction of water used conventionally reaches the disposal area, thus limiting sizes of water holding dam facilities and areas to be rehabilitated. Heat may also be recovered with direct water circulation from the thickening. READ MORE

  7. 15. 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
