    Determination of acoustic response of kerosene spray flames at atmospheric pressure and preheated air supply
    Influence of an oscillating air flow on the atomization process at the airblast atomization / Project: MAGISTER / Machine learning for Advanced Gas turbine Injection SysTems to Enhance combustoR performance. / Air transportation is expected to grow persistently over the next decades. Clean combustion technology for aircraft engines is a key enabler to reduce the impact of this growth on ecosystems and humans 19 health. The vision for European aviation is shaped by the Advisory Council for Aviation Research and Innovation in Europe in the Flight Path 2050 goals, which define stringent regulations on pollutant emissions. / To meet these goals, the major engine manufacturers develop lean premixed combustors operated at very high pressure. This development introduces a large risk for reduced reliability and lifetime of engines: pressure oscillations in the combustor called thermoacoustics. / Aviation industry encounters currently the fourth industrial revolution: cyber-physical systems analyze and monitor techn ...

    Numerical simulation and modeling of turbulent, reacting flows
    Numerical calculation of turbulent reacting flow / The process of combustion, i.e. the process in which chemical components at stongly exothermal (heat releasing) conditions are oxidised, in most technically relevant applications ist used to convert energy but also to convert mass (e.g. to convert pollutants or poisonous matters) or in a combination of both. / Beneath the (wanted) goals combustion also plays an unwanted role in the context of emission of pollutants (e.g nitrogen oxides, carbon monoxide, carbon dioxide, sulfur dioxide, ultra fine particlates) and invironmentally harmful release of heat Additionally there is another area of concern based on the fact that useable fossile fuels are limited and the widely accepted fact that combustion products (especially CO2) negatively influence the world climate: therefore search and investigation on the use of alternative, renewable fuels have come into focus in the last decades. / Model systems / Research in the area of combustion technology starts by ...

    Untersuchung der Zündung unter Subatmosphärischen Bedingungen
    " Investigation of Ignition in Sub atmospheric Conditions" / This work is part of the "SOPRANO" EU project. / Motivation / The ability to re-ignite after flame extinguishing is critical for flight safety. One reason that makes difficult the relight process of the engine is the low temperature and low pressure, which slows the evaporation of the atomized fuel and limits the concentration of the oxygen and therefore the reaction rates. / The better understanding of the re-ignition process has a fundamental importance for the development of combustion champers for jet engines, since it allows the combustion chamber to be reduced, thus reducing C02 emissions due to the smaller engine mass. / In addition, the transition from RQL (Reach Quench Lean) concept to LPP (Lean-Premix-Prevapourised) has turned the scientific community to intensive research on the ignition phenomena because of the decreasing of residence time in the primary zone due to the increasing amount of the combustion air mass flux (up to 60% of ...

    Energy Efficient Coil Coating Process
    Energy Efficient Coil Coating Process / Coil coating is an important industrial process applied in a major part of industrial steel and metal alloy production and associated with big facilities and large primary energy consumption. / A major part of the overall plant size and the energy demand of coil coating facilities is associated with the drying/curing process that occur inside a curing oven, which is the bottleneck concerning the increase of the production capacity. In this drying/curing process, organic solvents are vaporized from the applied liquid coating film and since they are flammable, the usually applied curing ovens with convective air drying technology have to be operated far below the Low Explosive Limit (LEL), due to safety constraints. / ECCO proposes a novel solution for the curing oven operation, which can not only drastically increase the compactness and energetic efficiency of the system, but leads to an increased production flexibility due to a fuel-flexible, modular and potentially ...

    Development of reaction mechanisms by parameter identification of subsystems
    Development of Reaction Mechanism by Quantum Chemistry methods / Main Objectives / Application of computational quantum chemistry (ab inito and DFT calculations) is used to estimation of thermochemical properties and kinetic parameters of small and large species, including biochemicals, large aromatic intermediates in soot formation, carbon nanotubes and many other systems. / Introduction / Aromatic and poly-aromatic compounds are important components of fuels. They are also formed in pyrolysis reactions and in fuel rich regions of flames and other thermal systems, where they are considered important precursors and intermediates in soot and PAH formation. The decomposition products of these species in combustion and oxidation reactions involve the incorporation of oxygen through reactions with oxygenated radicals and with molecular oxygen forming species like hydroperoxides or unsaturated oxy-hydrocarbon. / This work involves the development of an extensive thermochemical property data base on unsaturated ...

    Numerical simulation of wet biomass carbonization in tubular reactors
    1CNumerical simulation of wet biomass carbonization in tubular reactors 1D / Biomass Steam Processing (BSP) is a steam assisted slow pyrolysis aims to densify the energy content of lignocellulosic feedstocks through a thermochemical conversion process. Evolution of BSP is the outcome of several years of experimental investigation on different processes and scales. Complexity of the multi-scale nature of biomass feedstock and uncertainty about chemical reactions as well as multiphase flow of educts and products in the reactor make these processes very difficult to be predicted and understood precisely. Development of this process can have a positive influence on the localizing of energy densification plants for biomass residues as an economical alternative energy source. BSP can be a profitable waste-to-energy strategy and ecological solution for biological waste disposal issues. / The proposed research project will gradually develop a modular program for the numerical simulation of solid transport, heat tran ...

    Modellierung der partiellen Oxidation von Methan
    Das Thema der numerischen Modellierung der partiellen Oxidation von Methan wird am Institut für Verbrennungstechnik in dem folgenden Kontakt wissenschaftlich Untersucht. / Die partielle Oxidation / In der Verbrennungstechnik stellt die partielle Oxidation einen Sonderfall dar. Im Gegensatz zur 1Cklassischen 1C Verbrennungstechnik wird der Einsatzstoff, oder auch Brennstoff, mehrheitlich nicht in Wasser und Kohlenstoffdioxid umgesetzt. Damit der Brennstoff nicht mehrheitlich zu Wasser und Kohlenstoffdioxid reagiert wird der Sauerstoffanteil im umzusetzenden Brennstoff-/Oxidatorgemisch geringer als in einer stöchiometrischen Mischung gehalten. Wird eine solche unterstöchiometrische Mischung aus Methan und Luft, oder alternativ auch reinem Sauerstoff entzündet laufen eine Vielzahl von Teilreaktionen ab. Diese führen neben den 1Cklassischen 1C Verbrennungsprodukten wie Wasser und Kohlenstoffdioxid zu weiteren Spezies wie beispielsweise Wasserstoff, Kohlenstoffmonoxid, höhere Kohlenwasserstoffe sowie fester Kohlenst ...

    Experimentelle Untersuchung der Rußentstehung und Oxidation in einer RQL Triebwerksbrennkammer
    Innerhalb des von der Europäischen Kommission geförderten Projekts SOPRANO (Soot Processes and Radiation in Aeronautical inNOvative combustors) soll die Rußentstehung moderner Flugzeugtriebwerke untersucht werden. / Im Zuge des Teilprojekts 1EGeneration of a validation data set for complex fuels on semi-technical scale 1D wird hierfür eine Modellbrennkammer aufgebaut um die Rußentstehung bei der Verbrennung von Kerosin zu untersuchen. Die hierbei gewonnenen Ergebnisse sollen innerhalb des Projekts genutzt werden um Modelle zur Rußentstehung zu validieren. / Brennkammer / Die Brennkammer wird nach dem RQL (Rich-Quench-Lean) Prinzip konstruiert. Dies bedeutet, dass zunächst ein fettes Brennstoff-Luft Gemisch verbrannt und anschließend sehr schnell mit reichlich Luft zu einem mageren Gemisch verdünnt wird. Durch das Vermeiden von stöchiometrischer Verbrennung und den damit niedrigeren Temperaturen sowie durch den Mangel an Sauerstoff in der primären Zone kann so die Entstehung von umweltschädlichen Stickoxiden ...
