Kawasaki Heavy Industries, Ltd. (KHI) has research and development projects for future hydrogen society; production of hydrogen gas, refinement and liquefaction for transportation and storage, and utilization with gas turbine / gas engine for the generation of electricity. In the development of hydrogen gas turbines, a key technology is the stable and low NOx hydrogen combustion, especially Dry Low Emission (DLE) or Dry Low NOx (DLN) hydrogen combustion. Due to the large difference in the physical properties of hydrogen compared to other fuels such as natural gas, well established gas turbine combustion systems cannot be directly applied for DLE hydrogen combustion. Thus, the development of DLE hydrogen combustion technologies is an essential and challenging task for the future of hydrogen fueled gas turbines. The DLE Micro-Mix combustion principle for hydrogen fuel has been in development for many years to significantly reduce NOx emissions. This combustion principle is based on cross-flow mixing of air and gaseous hydrogen which reacts in multiple miniaturized "diffusion-type" flames. The major advantages of this combustion principle are the inherent safety against flashback and the low NOx-emissions due to a very short residence time of the reactants in the flame region of the micro-flames.}, language = {en} } @article{TeumerCapitainRossJonesetal.2018, author = {Teumer, T. and Capitain, C. and Ross-Jones, J. and Tippk{\"o}tter, Nils and R{\"a}dle, M. and Methner, F.-J.}, title = {In-line Haze Monitoring Using a Spectrally Resolved Back Scattering Sensor}, series = {BrewingScience}, volume = {71}, journal = {BrewingScience}, number = {5/6}, publisher = {Fachverlag Hans Carl}, address = {N{\"u}rnberg}, issn = {1613-2041}, pages = {49 -- 55}, year = {2018}, abstract = {In the present work an optical sensor in combination with a spectrally resolved detection device for in-line particle-size-monitoring for quality control in beer production is presented. The principle relies on the size and wavelength dependent backscatter of growing particles in fluids. Measured interference structures of backscattered light are compared with calculated theoretical values, based on Mie-Theory, and fitted with a linear least square method to obtain particle size distributions. For this purpose, a broadband light source in combination with a process-CCD-spectrometer (charge ? coupled device spectrometer) and process adapted fiber optics are used. The goal is the development of an easy and flexible measurement device for in-line-monitoring of particle size. The presented device can be directly installed in product fill tubes or vessels, follows CIP- (cleaning in place) and removes the need of sample taking. A proof of concept and preliminary results, measuring protein precipitation, are presented.}, language = {en} } @article{Thomas2018, author = {Thomas, Axel}, title = {Technologiezentren in der Aachener Region - Retrospektiven und Perspektiven}, series = {VM Verwaltung und Management}, volume = {24}, journal = {VM Verwaltung und Management}, number = {3}, publisher = {Nomos}, address = {Baden-Baden}, issn = {0947-9856}, doi = {10.5771/0947-9856-2018-3-147}, pages = {147 -- 156}, year = {2018}, language = {de} } @article{Thomas2018, author = {Thomas, Axel}, title = {Zielerreichungen der Technologie- und Gr{\"u}nderzentren aus Sicht der kommunalen Finanzwirtschaft - dargestellt am Beispiel der Aachener Region}, series = {Der Gemeindehaushalt}, volume = {119}, journal = {Der Gemeindehaushalt}, number = {7}, publisher = {Kohlhammer}, address = {Stuttgart}, issn = {0340-3645}, pages = {149 -- 155}, year = {2018}, language = {de} } @inproceedings{ThurnGebhardt2018, author = {Thurn, Laura and Gebhardt, Andreas}, title = {Strategy of Education on Materials for Students}, series = {Conference Proceedings: „New Perspectives in Science Education"}, booktitle = {Conference Proceedings: „New Perspectives in Science Education"}, address = {Florence, Italy}, isbn = {978-88-6292-976-9}, pages = {156 -- 161}, year = {2018}, language = {en} } @book{Timme2018, author = {Timme, Michael}, title = {BGB Crashkurs: der sichere Weg durch die Pr{\"u}fung}, edition = {5.
