1. Quantitative Spectroscopy of Gas Phase Reactions at Elevated Temperatures
Sammanfattning : Gas phase reactions at elevated temperatures are versatile tools for material manufacturing and energy conversion. They are of great commercial interest, but they often entail hazardous impacts on the environment. There is consequently a pronounced need for the further develpment of processes utilising these types of reactions. LÄS MER
2. Rotational Coherent Anti-Stokes Raman Spectroscopy: Experimental and Theoretical Developments in Gas-phase Thermometry
Sammanfattning : Dual-broadband pure rotational coherent anti-Stokes Raman spectroscopy was investigated in terms of thermometry and species concentration measurement for studies of combustion. The modelling of rotational CARS spectra under conditions of high pressure at room temperature was investigated. LÄS MER
3. Development and Application of Pure Rotational CARS for Reactive Flows
Sammanfattning : The thesis deals with the further development of pure rotational coherent anti-Stokes Raman spectroscopy (RCARS) for improving the capabilities of gas phase thermometry. The main effort has been to make the technique more robust when employed under a wide range of temperatures and operational conditions. LÄS MER
4. Phosphor Thermometry on Surfaces - A Study of its Methodology and its Practical Applications
Sammanfattning : Phosphor Thermometry is a term describing an optical measurement technique for remote temperature sensing. Its working principle is based on the temperature-sensitive emission characteristics of certain ceramic substances termed thermographic phosphors. LÄS MER
5. Optical Diagnostics for Quantitative Potassium Chemistry in Biomass Thermochemical Conversion Processes
Sammanfattning : Biomass is an essential sustainable and carbon-neutral energy source. Through thermochemical conversion processes, such as combustion and gasification, biomass can generally be used in boilers to provide heat and/or power. Biomass fuels contain varying amounts of potassium, chlorine and sulfur. LÄS MER
