16. Development of Multi-Dimensional Laser Techniques for In-situ Combustion Diagnostics
Sammanfattning : Multi-dimensional, laser-based measurements of quantities important for obtaining a better understanding of combustion processes, particularly of temperature and of species distributions, were performed using laser-induced fluorescence (LIF). The main purpose of the temperature experiments was to investigate the potential of employing a two-line atomic fluorescence technique (TLAF), using indium as the tracer species, in sooting environments such as in diesel engines.

17. Thermometry Using Laser-Induced Emission from Thermographic Phosphors: Development and Applications in Combustion
Sammanfattning : Temperature is a fundamental thermodynamic parameter used to describe physical, chemical and biological processes. Much effort is made to measure temperature accurately in a wide variety of applications, making temperature one of the most extensively measured parameters. LÄS MER
18. 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
19. Application of Laser Techniques in Combustion Environments of Relevance for Gas Turbine Studies
Sammanfattning : In the work presented in this thesis, different laser-based techniques were employed for measurements in different combustion devices. Laser-based techniques enable non-intrusive and in-situ measurements to be carried out, in which high spatial and temporal resolution can be obtained. LÄS MER
20. Optical Diagnostics of Non-thermal Plasmas and Plasma-assisted Combustion
Sammanfattning : Non-thermal plasma is regarded as a collection of free electrons, ions and neutral particles that are not at local thermodynamic equilibrium. The high-energetic electrons formed in non-thermal plasmas are capable of generating chemically active species and modifying chemical kinetics in practical applications. LÄS MER
