16. Laminar Burning Velocity and Development of a Chemical Kinetic Model for Small Oxygenated Fuels
Sammanfattning : The thesis work was performed with the aim of increasing knowledge and understanding of the combustion of oxygenated fuels and intermediates. This was accomplished in two steps: experimental measurements of the laminar burning velocity to expand current databases and development of a reaction mechanism. LÄS MER
17. Laser Diagnostics for Applications to In-Cylinder Engine Investigations
Sammanfattning : In the work presented in the thesis laser diagnostics was employed primarily in the investigation of engines, but was also used to study soot in flames. Quantitative measurements were performed for visualizing both in-cylinder soot formation and DME sprays in a combustion vessel. LÄS MER
18. High-speed optical and laser diagnostics - Internal combustion engines and gas turbine applications
Sammanfattning : Increasing demands to meet regulations on combustion emissions and their environmental impact, and the need to improve their efficiency in different applications, have been the centre of focus in research and industry for decades. Optical and laser diagnostics have been proven to be amongst the best available tools due to their remote nature and non-intrusiveness, high spatial and temporal resolution, and their ability to investigate combustion processes and emissions in ways unprecedented before.

19. Frequency Recognition Algorithm for Multiple Exposures : Snapshot imaging using coded light
Sammanfattning : The central challenge tackled in this thesis is the development of an optical imaging approach capable of multidimensional image capture of dynamic samples. Many conventional optical imaging approaches, which can obtain dimensional information such as spectral, polarisation, or volumetric, to name a few, about samples either employ sequential image capture or parallelised detector arrangements.

20. Towards Quantitative Diagnostics using Short-Pulse Laser Techniques
Sammanfattning : Laser based diagnostic tools have had an exploding impact on fundamental as well as applied research in a number of disciplines, such as biomedicine, physical chemistry etc over the last decades. Whereas fundamental research often investigate phenomena in extreme conditions, applied research aims at performing in-situ measurements, in order to understand the many aspects and entangled phenomena that affects the research of interest.
