Due to the 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 to dry low NOₓ (DLN) hydrogen combustion. The DLN micromix combustion of hydrogen has been under development for many years, since it has the promise to significantly reduce NOₓ emissions. This combustion principle for air-breathing engines is based on crossflow mixing of air and gaseous hydrogen. Air and hydrogen react in multiple miniaturized diffusion-type flames with an inherent safety against flashback and with low NOₓ emissions due to a very short residence time of the reactants in the flame region. The paper presents an advanced DLN micromix hydrogen application. The experimental and numerical study shows a combustor configuration with a significantly reduced number of enlarged fuel injectors with high-thermal power output at constant energy density. Larger fuel injectors reduce manufacturing costs, are more robust and less sensitive to fuel contamination and blockage in industrial environments. The experimental and numerical results confirm the successful application of high-energy injectors, while the DLN micromix characteristics of the design point, under part-load conditions, and under off-design operation are maintained. Atmospheric test rig data on NOₓ emissions, optical flame-structure, and combustor material temperatures are compared to numerical simulations and show good agreement. The impact of the applied scaling and design laws on the miniaturized micromix flamelets is particularly investigated numerically for the resulting flow field, the flame-structure, and NOₓ formation.}, language = {en} } @article{FunkeKeinzKustereretal.2017, author = {Funke, Harald and Keinz, Jan and Kusterer, K. and Haj Ayed, A. and Kazari, M. and Kitajima, J. and Horikawa, A. and Okada, K.}, title = {Development and Testing of a Low NOX Micromix Combustion Chamber for an Industrial Gas Turbine}, series = {International Journal of Gas Turbine, Propulsion and Power Systems}, volume = {9}, journal = {International Journal of Gas Turbine, Propulsion and Power Systems}, number = {1}, issn = {1882-5079}, doi = {10.38036/jgpp.9.1_27}, pages = {27 -- 36}, year = {2017}, abstract = {The Micromix combustion principle, based on cross-flow mixing of air and hydrogen, promises low emission applications in future gas turbines.

The numerical and experimental approach for considering variable fuel mixtures instead of recently investigated pure hydrogen is described. In the experimental studies, a first generation FuelFlex Micromix combustor geometry is tested at atmospheric pressure at gas turbine operating conditions corresponding to part- and full-load. The H2/CH4 fuel mixture composition is varied between 57 and 100 vol.\% hydrogen content. Despite the challenges flexible-fuel operation poses onto the design of a combustion system, the evaluated FuelFlex Micromix prototype shows a significant low NOx performance}, language = {en} } @article{FuestKotliarWalteretal.2014, author = {Fuest, Matthias and Kotliar, Konstantin and Walter, Peter and Plange, Niklas}, title = {Monitoring intraocular pressure changes after intravitreal Ranibizumab injection using rebound tonometry}, series = {Ophthalmic and physiological optics}, volume = {34}, journal = {Ophthalmic and physiological optics}, number = {4}, publisher = {Wiley-Blackwell}, address = {Oxford}, issn = {1475-1313 (E-Journal); 0275-5408 (Print)}, doi = {10.1111/opo.12134}, pages = {438 -- 444}, year = {2014}, language = {en} } @article{FuchsRitz2011, author = {Fuchs, Britta and Ritz, Thomas}, title = {Absatzkan{\"a}le kaum verkn{\"u}pft}, series = {IT-Mittelstand : IT-Business im Mittelstand}, volume = {2011}, journal = {IT-Mittelstand : IT-Business im Mittelstand}, number = {9}, publisher = {Medienhaus-Verlag}, address = {Bergisch-Gladbach}, pages = {16}, year = {2011}, language = {de} } @article{FrotscherStaat2014, author = {Frotscher, Ralf and Staat, Manfred}, title = {Stresses produced by different textile mesh implants in a tissue equivalent}, series = {BioNanoMaterials}, volume = {15}, journal = {BioNanoMaterials}, number = {1-2}, publisher = {De Gruyter}, address = {Berlin}, issn = {2191-4672 (E-Journal); 2193-066X (E-Journal); 0011-8656 (Print); 1616-0177 (Print); 2193-0651 (Print)}, doi = {10.1515/bnm-2014-0003}, pages = {25 -- 30}, year = {2014}, abstract = {Two single-incision mini-slings used for treating urinary incontinence in women are compared with respect to the stresses they produce in their surrounding tissue. In an earlier paper we experimentally observed that these implants produce considerably different stress distributions in a muscle tissue equivalent. Here we perform 2D finite element analyses to compare the shear stresses and normal stresses in the tissue equivalent for the two meshes and to investigate their failure behavior. The results clearly show that the Gynecare TVT fails for increasing loads in a zipper-like manner because it gradually debonds from the surrounding tissue. Contrary to that, the tissue at the ends of the DynaMesh-SIS direct may rupture but only at higher loads. The simulation results are in good agreement with the experimental observations thus the computational model helps to interpret the experimental results and provides a tool for qualitative evaluation of mesh implants.}, language = {en} } @article{FrotscherMuanghongDursunetal.2016, author = {Frotscher, Ralf and Muanghong, Danita and Dursun, G{\"o}zde and Goßmann, Matthias and Temiz Artmann, Ayseg{\"u}l and Staat, Manfred}, title = {Sample-specific adaption of an improved electro-mechanical model of in vitro cardiac tissue}, series = {Journal of Biomechanics}, volume = {49}, journal = {Journal of Biomechanics}, number = {12}, publisher = {Elsevier}, address = {Amsterdam}, issn = {0021-9290 (Print)}, doi = {10.1016/j.jbiomech.2016.01.039}, pages = {2428 -- 2435}, year = {2016}, abstract = {We present an electromechanically coupled computational model for the investigation of a thin cardiac tissue construct consisting of human-induced pluripotent stem cell-derived atrial, ventricular and sinoatrial cardiomyocytes. The mechanical and electrophysiological parts of the finite element model, as well as their coupling are explained in detail. The model is implemented in the open source finite element code Code_Aster and is employed for the simulation of a thin circular membrane deflected by a monolayer of autonomously beating, circular, thin cardiac tissue. Two cardio-active drugs, S-Bay K8644 and veratridine, are applied in experiments and simulations and are investigated with respect to their chronotropic effects on the tissue. These results demonstrate the potential of coupled micro- and macroscopic electromechanical models of cardiac tissue to be adapted to experimental results at the cellular level. Further model improvements are discussed taking into account experimentally measurable quantities that can easily be extracted from the obtained experimental results. The goal is to estimate the potential to adapt the presented model to sample specific cell cultures.}, language = {en} } @article{FrotscherKochStaat2015, author = {Frotscher, Ralf and Koch, Jan-Peter and Staat, Manfred}, title = {Computational investigation of drug action on human-induced stem cell derived cardiomyocytes}, series = {Journal of biomechanical engineering}, volume = {Vol. 137}, journal = {Journal of biomechanical engineering}, number = {iss. 7}, publisher = {ASME}, address = {New York}, issn = {1528-8951 (E-Journal); 0148-0731 (Print)}, doi = {10.1115/1.4030173}, pages = {071002-1 -- 071002-7}, year = {2015}, language = {en} } @article{FrohbergAnik1983, author = {Frohberg, Martin G. and Anik, Sabri}, title = {The application of a quadi-chemical lattice model to binary metallic solvents containing oxygen in higher concentrations}, series = {Zeitschrift f{\"u}r Metallkunde}, volume = {74}, journal = {Zeitschrift f{\"u}r Metallkunde}, number = {10}, issn = {0044-3093}, pages = {665 -- 666}, year = {1983}, language = {en} } @article{FrohbergAnik1985, author = {Frohberg, Martin G. and Anik, Sabri}, title = {The calculation of component activities of binary metallic melts from their gas solubilities}, series = {Zeitschrift f{\"u}r Metallkunde}, volume = {76}, journal = {Zeitschrift f{\"u}r Metallkunde}, number = {2}, issn = {0044-3093}, pages = {135 -- 137}, year = {1985}, language = {en} } @article{FrohbergAnik1984, author = {Frohberg, Martin G. and Anik, Sabri}, title = {{\"U}ber die Voraussetzungen der Wasserstoffl{\"o}slichkeit in bin{\"a}ren Eisenschmelzen}, series = {Archiv f{\"u}r das Eisenh{\"u}ttenwesen : Fachberichte}, volume = {55}, journal = {Archiv f{\"u}r das Eisenh{\"u}ttenwesen : Fachberichte}, number = {2}, issn = {0003-8962}, pages = {45 -- 48}, year = {1984}, language = {de} } @article{FrohbergAnik1985, author = {Frohberg, Martin G. and Anik, Sabri}, title = {Thermodynamic relations between component activities and gas solubilities in binary metallic systems}, series = {Berichte der Bunsengesellschaft f{\"u}r physikalische Chemie}, volume = {89}, journal = {Berichte der Bunsengesellschaft f{\"u}r physikalische Chemie}, number = {2}, issn = {0940-483X}, pages = {130 -- 134}, year = {1985}, language = {en} } @article{FrohbergAnik1984, author = {Frohberg, Martin G. and Anik, Sabri}, title = {Die Vorausbestimmung der Stickstoffl{\"o}slichkeit in bin{\"a}ren Eisenschmelzen}, series = {Archiv f{\"u}r das Eisenh{\"u}ttenwesen : Fachberichte}, volume = {55}, journal = {Archiv f{\"u}r das Eisenh{\"u}ttenwesen : Fachberichte}, number = {8}, issn = {0003-8962}, pages = {365 -- 367}, year = {1984}, language = {de} } @article{FrohbergAnik1986, author = {Frohberg, Martin G. and Anik, Sabri}, title = {Untersuchungen zum L{\"o}sungsverhalten von Sauerstoff in Metallschmelzen}, series = {Neue H{\"u}tte : metallurgisch-metallkundliche Fachzeitschrift f{\"u}r Forschung und Praxis}, volume = {31}, journal = {Neue H{\"u}tte : metallurgisch-metallkundliche Fachzeitschrift f{\"u}r Forschung und Praxis}, number = {7}, issn = {0028-3207}, pages = {255 -- 258}, year = {1986}, language = {de} } @article{FrohbergAnik1986, author = {Frohberg, Martin G. and Anik, Sabri}, title = {Experimentelle Ergebnisse zum L{\"o}sungsverhalten von Sauerstoff in den Systemen Cu-O-Bi und Cu-O-Pb}, series = {Neue H{\"u}tte : metallurgisch-metallkundliche Fachzeitschrift f{\"u}r Forschung und Praxis}, volume = {31}, journal = {Neue H{\"u}tte : metallurgisch-metallkundliche Fachzeitschrift f{\"u}r Forschung und Praxis}, number = {9}, issn = {0028-3207}, pages = {344 -- 347}, year = {1986}, language = {de} } @article{FritzscheFaberSchwarzer2002, author = {Fritzsche, Ulrich and Faber, Christian and Schwarzer, Klemens}, title = {Vergleich der Ergebnisse des quasidynamischen und station{\"a}ren Kollektortests nach En 12975-2}, series = {Zw{\"o}lftes Symposium Thermische Solarenergie : 24. bis 26.
