1. Laser Sheet Imaging and Image Analysis for Combustion Research
Sammanfattning : This Thesis presents techniques that aim at exploiting the potential of image analysis and processing in order to solve problems of data reduction, interpolation, quantification, and interpretation within the field of experimental laser imaging of combustion processes. Combustion is the most important source of energy for power generation, heating, and transportation in the world today and its strong dominance is projected to continue in the foreseeable future.

2. Development and application of laser diagnostics - from laboratory devices towards practical combustion engines
Sammanfattning : For many decades, research work on combustion has been focused on improving combustion efficiency and reducing harmful emissions. Laser diagnostics is one of the best ways to investigate the combustion process and emission formation as it is non-intrusive and it has high spatiotemporal resolution. LÄS MER
3. High-speed 3D imaging of liquid jets, surfaces and respiratory droplets
Sammanfattning : Sprays are commonly found in, among other, combustion, agriculture and food processing. For each of these applications, the understanding of spray liquid dynamics is crucial for optimization of efficiency, accuracy, and robustness of the spray-system in use. LÄS MER
4. Fluid Dynamics in Gas-Liquid Stirred Tank Reactors: Experimental and Theoretical Studies of Bubble Coalescence
Sammanfattning : This work deals with studies of bubble coalescence in turbulent flows of gas-liquid stirred tank reactors. Coalescence plays an important role in determining bubble size distribution, on which flow and mass transfer in such reactors largely depend. LÄS MER
5. Dynamics of Fluid Particles in Turbulent Flows; CFD simulations, Model Development and Phenomenological Studies
Sammanfattning : The thesis investigates the dynamics of fluid particles in turbulent flows, which plays an important role in the chemical, pharmaceutical, food and petroleum industries. Phenomenological studies, new mathematical models for the breakup phenomena, and development of a simulation method for chemical reactors constitute the main parts of this thesis. LÄS MER
