1. Theory of microcapillarity. 1, Equilibrium and stability
Sammanfattning : Capillary porous systems. Thermodynamical equilibrium and stability water meniscus. Mathematical treatment. Effect of salts, osmotic pressure. LÄS MER
2. Capillarity and dynamic wetting
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. Mechanical processing for improved products made from Swedish hardwood
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. Capillarity and wetting of non-Newtonian droplets
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. Methods of measuring the moisture diffusivity at high moisture levels
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
