1. Interior Flow and Formation of Plain Orifice Sprays
Sammanfattning : This thesis will summarize recent experimental observations of spray formation in highly atomizing plainorifce sprays, the kind commonly produced by fuel injectors in compression ignition internal combustionengines. Two special interactions will be addressed in detail: primary atomization under elevated ambientpressures and temperatures and orifce ow effects on primary atomization. LÄS MER
2. Dissolved Air Flotation
Sammanfattning : Dissolved Air Flotation (DAF) is a well-established treatment method for water containing low density particles. The density-driven process is operated by the injection of water saturated with air under high pressure. At the pressure reduction microscopic air bubbles are formed. LÄS MER
3. Particle Coating in a Wurster Type Bed
Sammanfattning : The Wurster bed process is frequently used for film coating. In the Wurster bed, particles circulate in the equipment and are sprayed with a liquid which forms a coating when dry. The procedure is repeated until the desired characteristics of the coating layer are obtained. LÄS MER
4. Interacting particles and droplets at low Reynolds numbers
Sammanfattning : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. LÄS MER
5. Multiphase Contamination in Rock Fractures : Fluid Displacement and Interphase Mass Transfer
Sammanfattning : Multiphase flow and transport in fractured rock is of importance to many practical and engineering applications. In the field of groundwater hydrology an issue of significant environmental concern is the release of dense non-aqueous phase liquids (DNAPLs) which can cause long-term groundwater contamination in fractured aquifers.
