  1. 1. Atomic-scale modelling of interfaces in cemented carbides: wetting and strength

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Martin Gren; [2017]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; adhesion; density functional theory; hardmetals; cemented carbides; WC-Co; surfaces; interfaces; grain boundaries; wetting; phase boundaries;

    Abstract : Cemented carbides are composite materials of great technological and industrial importance. They have a unique combination of hardness and toughness and are therefore used widely as tool materials in applications where both high hardness and toughness are demanded. These applications include among others: mining, turning, cutting and milling. READ MORE

  2. 2. Hydrophobic surfaces: Effect of surface structure on wetting and interaction forces

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Petra M Hansson; KTH.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; hydrophobic surface; superhydrophobic surface; atomic force microscopy; surface forces; capillary forces; cavitaion; surface roughness; friction; wetting; confocal Raman; contact angles; surface preparation; Langmuir-Blodgett;

    Abstract : The use of hydrophobic surfaces is important for many processes both in nature and industry. Interactions between hydrophobic species play a key role in industrial applications such as water-cleaning procedures and pitch control during papermaking but they also give information on how to design surfaces like hydrophobic mineral pigments.

  3. 3. Capillarity and dynamic wetting

    University dissertation from Stockholm : KTH Royal Institute of Technology

    Author : Andreas Carlson; KTH.; [2012]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis capillary dominated two–phase flow is studied by means of nu- merical simulations and experiments. The theoretical basis for the simulations consists of a phase field model, which is derived from the system’s thermody- namics, and coupled with the Navier Stokes equations. READ MORE

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

    University dissertation from KTH Royal Institute of Technology

    Author : Yuli Wang; KTH.; [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
