1. Predictive Modeling of Lake Eutrophication
Sammanfattning : This thesis presents predictive models for important variables concerning eutrophication effects in lakes. The keystone is a dynamic phosphorus model based on ordinary differential equations. LÄS MER
2. Settling Mechanisms of Valuable Metal Droplets in Iron Silicate Slag
Sammanfattning : A significant source of copper losses from pyrometallurgical copper extraction is attributed to dissolved and entrained copper in discarded slag. Entrained copper can be recovered via pyrometallurgical slag cleaning in a settling furnace where the droplets settle under gravity. LÄS MER
3. Compositional variability of settling organic particles in non-tidal coastal and shelf enviroments
Sammanfattning : The coupling between the composition of settling organic particles and near-bed dynamics was studied in non-tidal coastal and shelf environments. Field investigations were made in Skagerrak and Limfjorden between 1990 and 1995. LÄS MER
4. Fluid mechanics of fibre suspensions related to papermaking
Sammanfattning : This thesis deals with fluid dynamic mechanisms related to papermaking, specif- ically: the initial dewatering mechanisms during roll-forming and fibre motion in sedimentation and in shear flow. Pressure and wire position measurements have been conducted in a model resembling the forming zone and the measured pressure distributions are shown to have more complex patterns than the simple model p / T/R (where T is the wire tension and R is the roll radius).

5. Suspensions of finite-size rigid particles in laminar and turbulent flows
Sammanfattning : Dispersed multiphase flows occur in many biological, engineering and geophysical applications. Understanding the behavior of suspensions is a difficult task. In the present work, we numerically study the behavior of suspensions of finite-size rigid particles in different flows. LÄS MER
