26. On Particle Transport and Turbulence Modification in Air-Particle Flows
Sammanfattning : The transport of particles by airflow was studied for two different flow cases, the transport of pulp fibres in a mat-forming process and the transport of pulp fibres and spherical particles in a horizontal pipe. The transport of pulp fibres in the mat-forming process is first considered. LÄS MER
27. MULTICOMPONENT SPRAY-TURBULENCE INTERACTION
Sammanfattning : Blended fuels are gaining importance in automotive industry owing to stringent legislations for emissions. It is important to understand the fuel spray formed as a consequence of injecting blended fuels into the engine (for direct injection engines) and also the influence of fuel spray on combustion properties.

28. A numerical study of two-fluid models for dispersed two-phase flow
Sammanfattning : In this thesis the two-fluid (Eulerian/Eulerian) formulation for dispersed two-phase flow is considered. Closure laws are needed for this type of models. We investigate both empirically based relations, which we refer to as a nongranular model, and relations obtained from kinetic theory of dense gases, which we refer to as a granular model. LÄS MER
29. Modelling of turbulent gas-particle flow
Sammanfattning : An Eulerian-Eulerian model for dilute gas-particle turbulent flows is developed for engineering applications. The aim is to understand the effect of particles on turbulent flows. The model is implemented in a finite element code which is used to perform numerical simulations. LÄS MER
30. Numerical Modelling of Dissolved Air Flotation
Sammanfattning : Dissolved Air Flotation (DAF), a well-established treatment method for water containing e.g. dissolved organic matter and Cryptosporidium, has previously been examined experimentally. However, most measuring techniques still suffer from disturbances from air bubbles and intrusion of the measuring equipment into the flow. LÄS MER
