1. The flow of pulp suspensions
Sammanfattning : Large quantities of pulp suspensions are handled in the pulp and paper industry and knowledge of their flow behaviour is very important in the design and operation of process equipment. Despite this, there is still a lack of a fundamental understanding of the mechanisms of the pulp suspension flow. LÄS MER
2. 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
3. Fluid mechanics of solid-liquid suspensions in stirred vessels : an experimental and numerical study
Sammanfattning : .... 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. Rheological Properties of Microfibrillated Cellulose
Sammanfattning : Cellulose has for a long time been used by man. It is renewable and an easily recyclable resource. Mostly it has been used in either its native form as wood or in the form of fibres. LÄS MER
