  1. 1. Theory of microcapillarity. 1, Equilibrium and stability

    Författare :Johan Claesson; Avdelningen för Byggnadsfysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Humidity; capillarity; Material; porosity; Physics; science; Surface; tension; Water; absorption capillarity; transfer; Fysicumarkivet A:1977:Claesson;

    Sammanfattning : Capillary porous systems. Thermodynamical equilibrium and stability water meniscus. Mathematical treatment. Effect of salts, osmotic pressure. LÄS MER

  2. 2. 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

  3. 3. Mechanical processing for improved products made from Swedish hardwood

    Författare :Jimmy Johansson; Dick Sandberg; František Hapla; Växjö universitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; capillarity; capillary transport; wood products; customer requirements; ecoeffectiveness; ; sawing pattern; star-sawing; the PrimWood Method; timber products; volume yield; water transport; Wood fibre and forest products; Träfiber- och virkeslära;

    Sammanfattning : Swedish hardwood is today used in the energy, pulp and mechanical hardwood industries. Only very small volumes of Swedish hardwood are, however, consumed by the mechanical industry that normally pays the highest timber price. LÄS MER

  4. 4. 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. 5. Methods of measuring the moisture diffusivity at high moisture levels

    Författare :Mårten Janz; Avdelningen för Byggnadsmaterial; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fukttransport; materialegenskaper; permeabilitet; teori; beräkningsmetoder; mätmetoder; byggmaterial; forskningsresultat;

    Sammanfattning : The purpose of this licentiate study is to analyze capillarity transport in building materials, and in order to do that, develop a new measurement method by which the moisture diffusivity at high moisture levels can be measured in an easy way.... LÄS MER
