6. Fluid Dynamics of a Wurster-type Fluidized Bed - A Numerical and Experimental Study
Sammanfattning : The fluid dynamics of a Wurster bed, a fluidized bed used in the pharmaceutical industry for the coating of small particles or pellets, is investigated numerically and experimentally. The main objective of the thesis is to obtain greater knowledge of the flow properties in the Wurster bed. LÄS MER
7. 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
8. Rheological modeling of particle flows in high shear granulation
Sammanfattning : High shear granulation is an important process in a wide variety of applications, more specifically in pharmaceutical industries as a basic step in the tableting process. The process includes two major steps: dry high shear granulation and wet high shear granulation. It aims at producing granules with a specific size and material composition. LÄS MER
9. Fluid Dynamics and Erosion in a Fluidized Bed for Energy Production. A Numerical and Experimental Study
Sammanfattning : This thesis presents an experimental and a numerical investigation of fluid dynamics and erosion of heat transfer tubes in fluidized beds for energy conversion. The objective is to obtain recommendations for suitable models that can be used to predict the fluid dynamics and material wastage of heat exchanger tubes in fluidized beds. LÄS MER
10. Fluid Dynamics and Granular Growth in High Shear Wet Granulation
Sammanfattning : High shear wet granulation is a key step in the manufacturing of tablets in the pharmaceutical industry. From the pharmaceutical industry’s point of view, there is a desire for predictive quantitative process models to be able to make in-silico process and scale-up simulations, which would shorten and reduce the cost of technology transfer from laboratory scale to manufacturing scale in drug development.
