21. Development of a 2D Temperature Measurement Technique for Combustion Diagnostics using 2-Line Atomic Fluorescence
Abstract : The present thesis is concerned with the development and application of a novel planar laser-induced fluorescence (PLIF) technique for temperature measurements in a variety of combusting flows. Accurate measurement of temperature is an essential task in combustion diagnostics, since temperature is one of the most fundamental quantities for the characterization of combustion processes.

22. Experimental investigation of premixed ammonia combustion at high Karlovitz number conditions
Abstract : This thesis aims to acquire deep knowledge on turbulent premixed combustion at high Karlovitz (Ka) number conditions with the help of laser-based diagnostic measurements.Considering that ammonia (NH3), as a carbon-free energy carrier, is a promising candidate for replacing conventional fossil fuels in the future, all the investigations in this work were carried out on ammonia/air premixed flames.

23. Lifetime Surface Phosphor Thermometry - Technique Developments, Sources of Error, and Applications
Abstract : Temperature is not only a fundamental aspect of everyday life, but it is also an essential metric for thermal conversion systems concerning efficiency, emissions, and component lifetime estimation. Therefore, a vast range of different methods to measure temperature has been developed. READ MORE
