The Micromix combustion takes place in several hundreds of miniaturized diffusion-type micro-flames. The major advantage is the inherent safety against flash-back and low NOx-emissions due to a very short residence time of reactants in the flame region. The paper gives insight into the Micromix design and scaling procedure for different energy densities and the interaction of scaling laws and key design drivers in gas turbine integration. Numerical studies, experimental testing, gas turbine integration and interface considerations are evaluated. The aerodynamic stabilization of the miniaturized flamelets and the resulting flow field, flame structure and NOx formation are analysed experimentally and numerically. The results show and confirm the successful adaption of the low NOx Micromix characteristics for a range of different nozzle sizes, energy densities and thermal power output.}, language = {de} } @inproceedings{FunkeKeinzHendrick2017, author = {Funke, Harald and Keinz, Jan and Hendrick, P.}, title = {Experimental Evaluation of the Pollutant and Noise Emissions of the GTCP 36-300 Gas Turbine Operated with Kerosene and a Low NOX Micromix Hydrogen Combustor}, series = {7th European Conference for Aeronautics and Space Sciences, EUCASS 2017}, booktitle = {7th European Conference for Aeronautics and Space Sciences, EUCASS 2017}, organization = {7th European Conference for Aeronautics and Space Sciences, EUCASS 2017-125, Milan, Italy, July 2017}, doi = {10.13009/EUCASS2017-125}, pages = {10 Seiten}, year = {2017}, language = {en} } @incollection{Wilke2017, author = {Wilke, Thomas}, title = {Ranson, Pierre}, series = {Allgemeines K{\"u}nstler-Lexikon.

However, integrating different methods still poses considerable challenges. To move beyond general recommendations for mixed-methods research, this chapter proposes to discuss methodological issues with respect to a particular research domain. Taking current studies on the transition to higher education as an example, the authors first provide an overview of the potentials and limitations of quantitative and qualitative methods in the research domain. Second, they show the need for a conceptual framework grounded in the theory of the research object to guide the integration of different methods and findings. Finally, an example study that investigates transition with regard to the interplay of the individual student and the institutional context serves to illustrate the guiding role of theory. The framework integrates different theoretical perspectives on transition, informs the selection of the research methods, and defines the nexus of the two strands that constitute the mixed-methods design. As the interplay of individual and context is of concern for teaching and learning in general, the example presented may be fruitful for the wider field of higher education research.}, language = {en} } @article{PeloniDachwaldCeriotti2017, author = {Peloni, Alessandro and Dachwald, Bernd and Ceriotti, Matteo}, title = {Multiple near-earth asteroid rendezvous mission: Solar-sailing options}, series = {Advances in Space Research}, journal = {Advances in Space Research}, number = {In Press, Corrected Proof}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0273-1177}, doi = {10.1016/j.asr.2017.10.017}, year = {2017}, language = {en} } @inproceedings{GrundmannMessBieleetal.2017, author = {Grundmann, Jan Thimo and Meß, Jan-Gerd and Biele, Jens and Seefeldt, Patric and Dachwald, Bernd and Spietz, Peter and Grimm, Christian D. and Spr{\"o}witz, Tom and Lange, Caroline and Ulamec, Stephan}, title = {Small spacecraft in small solar system body applications}, series = {IEEE Aerospace Conference 2017, Big Sky, Montana, USA}, booktitle = {IEEE Aerospace Conference 2017, Big Sky, Montana, USA}, organization = {IEEE Aerospace Conference}, isbn = {978-1-5090-1613-6}, doi = {10.1109/AERO.2017.7943626}, pages = {1 -- 20}, year = {2017}, language = {en} } @article{BarnatBosseMergner2017, author = {Barnat, Miriam and Bosse, Elke and Mergner, Julia}, title = {Forschungsbasierte Qualit{\"a}tsentwicklung f{\"u}r die Studieneingangsphase}, series = {Zeitschrift f{\"u}r Hochschulentwicklung (ZFHE)}, volume = {12}, journal = {Zeitschrift f{\"u}r Hochschulentwicklung (ZFHE)}, number = {3}, issn = {2219-6994}, doi = {10.3217/zfhe-12-03/05}, pages = {71 -- 91}, year = {2017}, language = {de} } @inproceedings{BarnatKnutzen2017, author = {Barnat, Miriam and Knutzen, S.}, title = {Erfolgsstrategien f{\"u}r organisationales Lernen}, series = {Hochschulwege 2015 : Wie ver{\"a}ndern Projekte die Hochschulen?
