  1. 6. Capillarity and dynamic wetting

    Författare :Andreas Carlson; Gustav Amberg; Laurent Limat; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : 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. LÄS MER

  4. 8. Capillarity and wetting of non-Newtonian droplets

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

    Sammanfattning : 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. LÄS MER

  5. 9. Wetting and Capillary Flow of Surfactant Solutions and Inks

    Författare :Maria von Bahr; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; AKD; ink-jet printing; paper; penetration; absorption; adsorption; hydrophobicity; nonionic; surfactant; spreading; dynamic wetting;

    Sammanfattning : This thesis presents results of a series of experimental studies on the spreading dynamics of small drops of complex solutions on solid surfaces. The capillary flow dynamics of complex solutions have also been investigated. LÄS MER

  7. 10. Interfacial behaviour of surfactants and enzymes: studies at model surfaces

    Författare :Olaspers Jonny Eriksson; Fysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Surface and boundary layery chemistry; gränsskikt; enzymatic degradation; cellulase; model film; cellulose; QCM; ellipsometry; surfactant; three-phase contact line; adsorption; wetting; Ytkemi;

    Sammanfattning : This thesis presents results from experimental studies of the interfacial behaviour of surfactants and enzymes at model surfaces. The main technique used throughout the work was ellipsometry. LÄS MER
