1. Near-Field Study of Multiple Interacting Jets : Confluent Jets
Abstract : This thesis deals with the near-field of confluent jets, which can be of interest in many engineering applications such as design of a ventilation supply device. The physical effect of interaction between multiple closely spaced jets is studied using experimental and numerical methods. READ MORE

2. Interacting particles and droplets at low Reynolds numbers
Abstract : The overall purpose with this work is to study the flow past particles and droplets using numerical simulations. Especially the interaction among particles and droplets have been a main objective as the results are to be used in order to improve already existing spray models. READ MORE

3. Turbulence Modelling of Flows Related to Wall-Cooling Applications
Abstract : Engineering flows are generally characterised by complex strain field and turbulence structure arising from a combination of shear, curvature, separation and recirculation etc. Under such flow conditions, transport by turbulent velocity fluctuations can make a significant contribution to the transport of momentum, heat and mass.

4. Numerical Investigation of Turbulent Fluid Flow and Heat Transfer in Complex Ducts
Abstract : Th need for a reliable and reasonable accurate turbulence model without specific convergence problem for calculating duct flows in industrial applications has become more evident. In this study a general computational method has been developed for calculating turbulent quantities in any arbitrary three dimensional duct. READ MORE

5. Computational Analysis of Heat Transfer and Fluid Flow with Relevance for IC-Engine Cooling
Abstract : Modern IC-engines produce more power per displaced volume and operate at higher combustion pressures and temperatures. In addition, engine structure materials such as aluminium and magnesium alloys, which are more sensitive to thermal loads, are more commonly used. READ MORE
