1. Stability analysis of channel flow laden with small particles
Sammanfattning : This thesis deals with the stability of particle laden flows. Both modal and non-modal linear analyses have been performed on two-way coupled particleladen flows, where particles are considered spherical, solid and either heavy or light. When heavy particles are considered, only Stokes drag is used as interaction term. LÄS MER
2. Investigations of Flow Patterns in Ventilated Rooms Using Particle Image Velocimetry : Applications in a Scaled Room with Rapidly Varying Inflow and over a Wall-Mounted Radiator
Sammanfattning : This thesis introduces and describes a new experimental setup for examining the effects of pulsating inflow to a ventilated enclosure. The study aimed to test the hypothesis that a pulsating inflow has potential to improve ventilation quality by reducing the stagnation zones through enhanced mixing. LÄS MER
3. Transition in Particle-laden Flows
Sammanfattning : This thesis presents the study of laminar to turbulent transition of particle laden flows. When a flow becomes turbulent, the drag increases one order of magnitude compared to a laminar flow, therefore, much research is devoted to understand and influence the transition. LÄS MER
4. 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
5. Shaping of Food Microstructures
Sammanfattning : Shape, the shaping process and the functionality of shape for food microstructure are the focus of this thesis. Shape is one of the parameters that influences the microstructure functionality; hence microstructure shape optimisation is an interesting task in the development of new functional materials and processes, especially for food, in which structure-related texture is an essential part of the product.
