1. Phase Doppler Anemometry in Unsteady Two-Phase Flow: A Novel Post-Processing Data Algorithm
Abstract : This thesis presents a novel method to estimate particle fluctuations in unsteady two-phase flow using phase Doppler anemometry (PDA). A comprehensive derivation and asuccessful validation of a PDA data post-processing algorithm are given. READ MORE

2. 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

3. Fluid and suspension hydrodynamics in the impeller discharge flow of stirred tanks
Abstract : The hydrodynamics of an agitated tank have been studied byphase-Doppler anemometry. The focus is on the impeller anddischarge region of a 45o pitched blade turbine (PBT). Thestudy includes agitation of pure water as well as of a dilutesuspension of process particles. READ MORE

4. Characterization of Gasoline Spray-Wall Interactions
Abstract : Interest in spray-wall interactions has intensified recently because of the development of direct injection spark ignition engines. In this type of engine, impingement of the spray on the piston and cylinder walls leads to increased emissions of hydrocarbons and soot. READ MORE

5. Experimental measurements of water mist systems and implications for modelling in CFD
Abstract : The use of water mist for fire extinguishment has increased rapidly in recent years. The main reason is the abandonment of halon-based extinguishing systems in favour of environmentally friendlier systems. Furthermore the use of water mist systems has spread from mainly marine applications to also include the protection of buildings. READ MORE
