1. On the modelling of turbulent flow and mixing in stirred reactors
Abstract : This thesis concerns the numerical simulations and modelling of the flow structure and scalar transport in stirred reactors. For this Large Eddy Simulations (LES) have been used. The flow situation in a stirred reactor includes several flow phenomena that are not well predicted by "standard" two-equation models, e.g. READ MORE

2. Continuum modelling of particle flows in high shear granulation
Abstract : High shear granulation is an important process in the pharmaceutical industry. The aim of the process is to produce granules with specific properties, like size and hardness, from powder mixtures. The properties of the granules are determined by the flow field in the mixer. READ MORE

3. Disintegration of Lime Mud Particles during the Causticizing Operation
Abstract : It is of essential importance that the white liquor used in processing wood chips to produce pulp in the sulphate pulp process is of high and uniform quality. The white liquor is, together with lime mud, produced in the causticizing plant where sodium carbonate is causticized with lime, slaked in green liquor. READ MORE

4. Fluid and Solid Particle Dynamics in Stirred Vessels
Abstract : The present thesis deals with the fluid dynamics of stirred vessels and particularly those that are to be used in conjunction with solids suspensions. Stirred vessels are very common in the process industry and large amounts of energy can be saved by optimising their operation. READ MORE
