21. Aero Engine Intercooling
Abstract : Intercooling has the potential to provide a shortcut to the next generation aero engines with higher bypass ratio (BPR), higher overall pressure ratio (OPR) and higher turbine inlet temperature (TIT) by lowering the high pressure compressor (HPC) delivery temperature. To be able to establish a systematic understanding of aero engine intercooling, the heat transfer and pressure loss characteristics of a given intercooler architecture need to be known in the parameter range anticipated for the engine optimization.

22. Laser-Based Investigations of Combustion Phenomena in Gas Turbine Related Burners
Abstract : Experiments were performed on various combustion devices to investigate the flames employing different optical measurement techniques under atmospheric pressure conditions. Non-intrusive laser-based techniques provided in-situ information concerning different parameters of the combustion process, with a high degree of temporal and spatial resolution. READ MORE

23. Laser Sheet Imaging and Image Analysis for Combustion Research
Abstract : 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.

24. Experimental investigation of flows related to gas turbine combustion
Abstract : The notion of "global warming" has become a major public-domain concept as an environmental threat to our future on earth. Independently of the accuracy of existing prediction of combustion emissions on the climate on earth, the concept of reducing combustion emissions has been an important political driving force in imposing more and more severe restrictions on harmful emissions from combustion.

25. Experimental and Numerical Investigations of Flames Stabilized by Swirl Flow and Bluff-body:Flame Structures and Flame Instabilities
Abstract : Combustion and its control are essential to our existence on this planet since we knew it. Nowadays, the largest share of the world’s electricity and most of our transportation systems are powered by combustion. In addition, industrial processes also rely heavily upon combustion. READ MORE
