The resulting cluster-based network modelconstitutes a deterministic-stochastic grey-box model resolving the coherent-structureevolution. This model is motivated by limit-cycle dynamics, illustrated for the chaoticLorenz attractor and successfully demonstrated for the laminar two-dimensional mixinglayer featuring Kelvin-Helmholtz vortices and vortex pairing, and for an actuatedturbulent boundary layer with complex dynamics. Cluster-based network modelling opensa promising new avenue with unique advantages over other model-order reductions basedon clustering or proper orthogonal decomposition.},

Following previous burner characterization, the current study investigates the heat transfer conditions in the combustion chamber wall. To this end, a carefully controlled co-flow of air is used to cool the combustion chamber in an annular duct, which surrounds it. Temperature measurements enable the evaluation of the heat flux from the combustor flow to the walls, local wall temperatures, and the Nusselt numbers on the hot and the cold side. The extremely high wall temperatures, caused by the H2/O2 flame, can be reduced by steam dilution down to approximately 900 K. Even better cooling could be reached by using the dilution steam as the coolant before it flows to the plenum. The Nusselt numbers at the inner combustion chamber wall are in the order of 10-50 and increase with the thermal power and the steam dilution ratio.},

   volume = {32},
   number = {9},
   pages = {1-24},
   abstract = {We propose a cavity as an actuator to actuate the supersonic mixing layer downstream a thick splitter plate. The cavity-actuated case at Re = 1.73 \(\times\) 105 is simulated using large eddy simulation. The forced dynamics is resolved by the cluster-based network model (CNM) from a probabilistic point of view. Introducing a cavity obtains a 50\% increase in the growth rate of vorticity thickness. The recirculation region immediately downstream the trailing edge of the splitter plate is largely reduced, which contributes to the advanced and fast growth of the redeveloping mixing layer. The cavity oscillation induces three-dimensional features that are beneficial to the small-scale mixing. Spectral analysis reveals that the cavity-actuated flow field exhibits the phenomena of the strict frequency-lock and temporal mode-switching. The CNM successfully resolves the intermittent dynamics of the supersonic mixing layer using only ten centroids. The CNM's outcomes reveal two flow regimes of the unforced case: the Kelvin-Helmholtz vortex and vortex pairing. The cavity oscillation significantly affects the flow patterns of the centroids, which exhibit flow structures closely associated with the wake mode and shear-layer mode of the cavity oscillations. The dynamics of the cavity-actuated case is tamed into a strictly periodic transition loop among ten clusters undergoing the cyclic motion of the cluster energy fluctuation from the maximum to the minimum. Each centroid of the cavity-actuated case transports much more turbulent kinetic energy than that of the unforced case. Overall, the cavity-actuated attractor gets a 3.27 times increase in the energy fluctuation.},

Wind tunnel investigations at different Reynolds numbers in the subcritical, critical, and supercritical flow regime were performed, in addition to investigations using wall-mounted cylinders. Furthermore, the impact of insulator sheds made of flexible material was analyzed. For a better understanding of the aerodynamic behavior of the insulators when mounted on trains, different boundary conditions representing realistic configurations as found on the roof of trains were simulated. From the measured drag, the energy demand to overcome the aerodynamic resistance of different types of insulators was calculated. Depending on the above mentioned boundary conditions, a noticeable contribution of the insulators to the entire train's aerodynamic drag could be observed. With flexible insulator sheds, a further increased air resistance was observed with the onset of fluttering. Similar to the cylinder, the aerodynamic behavior of the insulators depends on the respective Reynolds number.},

These conditions include surface waves, cavitation and submergence depth. The experiments were carried out in the shallow water towing tank of the Technische Universit{\"a}t Berlin. It is shown that outside a critical Froude number range of about 0.2&thinsp;<&thinsp;Fr&thinsp;<&thinsp;1.2 the impact of the surface waves can be neglected and no cavitation appears in the velocity range investigated. Furthermore, a correction method is proposed taking into account the bias through surface waves at small submergence and thus allowing for a wider Froude number range. The data obtained in the towing tank are found to be in excellent agreement to other investigation methods.},

   year = {2017},
   month = {12},
   pages = {108},
   abstract = {The focus of this study is the combustion of hydrogen in air as it relates to typical gas turbine engines. Hydrogen-air combustion occurs in the absence of any carbon-based emissions and the only combustion products are water vapor and oxides of nitrogen (NOx). However, due to the very low flammability limit of hydrogen, it can be burned at much lower equivalence ratios than typical hydrocarbon fuels, resulting in excellent low NOx potential. Lean premixed combustion of low reactivity fuels, such as natural gas, is nowadays state of the art in stationary gas turbines. In the long term, it is also a promising approach for aero engines. For lean premixed combustion, with increasing fuel reactivity lean blow out limits are extended but the disposition for flashback, an undesired event of upstream flame propagation, is increased. Therefore, combustor design strategies that are applied for conventional fuels have to be revisited in case of hydrogen, which represents the upper end of the scale of high reactivity fuels. The current thesis aims at developing a combustor design that is capable of safely operating on hydrogen-air mixtures up to stoichiometric conditions while meeting strict emission regulations. To this end, several measures affecting the flashback resistance of a hydrogen-air combustor are investigated. In addition to their effect on flashback resistance, all measures are evaluated with respect to their impact on fuel-air mixing which directly affects NOx emissions. Unlike most previous investigations on hydrogen-air combustion, the current investigations are conducted at partially premixed instead of perfectly premixed conditions. This poses a challenging task with respect to achieving flashback resistance as well as low \textbackslashmathrm\{NO\(_{x\}}\) emissions with limited premixing space and time. Experimental investigation of non-reacting and reacting combustor flow fields of a partially premixed model combustor were conducted using particle image velocimetry in an atmospheric combustor tests rig. Results reveal a strong influence of geometric modifications and fuel momentum on the combustor flow field. Stability maps were recorded that allow for comparison of the operational range of different combustor geometries with respect to flashback and lean blow out. It was shown that already moderate flow rates of a central non-swirling air jet significantly extend the flashback limits, while the lean blow out limits remained unaffected. Moreover, recordings of planar laser-induced fluorescence of the hydroxyl radical (OH-PLIF) within the flame revealed that, the axial location of the upstream flame front, x\(_{f}\), constitutes a telling estimator for flashback resistance. At the investigated conditions, x\(_{f}\) is shifted downstream with increasing equivalence ratio due to the added momentum of the fuel flow. Thereby, the local gain in axial velocity due to fuel momentum supersedes any parallel augmentation in the turbulent flame speed. This has been identified as a driving mechanism affecting the combustor stability limit.Performance and emissions data facilitate the conclusion that the desired flashback-safe operation at very low NOx emissions at ambient pressure and relevant combustor inlet temperatures is feasible. Der Fokus dieser Arbeit liegt auf der experimentellen Untersuchung von Ma{\ss}nahmen zur Gew{\"a}hrleistung der sicheren und schadstoffarmen Verbrennung von Wasserstoff mit Luft in einer Gasturbine. Die Verbrennung von Wasserstoff mit Luft geschieht ohne den Aussto{\ss} jeglicher Kohlenwasserstoffe, sodass sich das Abgas ausschlie{\ss}lich aus Wasserdampf und Stickoxiden zusammensetzt. Der Stickoxidanteil kann dabei auf ein Minimum begrenzt werden da Wasserstoff aufgrund seiner weiten Z{\"u}ndgrenzen extrem mager verbrannt werden kann. Mager vorgemischte Verbrennung, wie sie heutzutage bereits in station{\"a}ren Gasturbinen zum Standard geh{\"o}rt, stellt mittelfristig auch einen vielversprechenden Ansatz f{\"u}r Fluggasturbinen dar. Der Einsatz hochreaktiver Brennstoffe, zum Beispiel wasserstoffreiche Synthesegase oder reiner Wasserstoff, erweitert zwar einerseits deutlich den mageren Betriebsbereich. Andererseits erh{\"o}ht sich auch enorm das Risiko des Auftretens von Flammenr{\"u}ckschlag, welcher zu massiver Besch{\"a}digung von Bauteilen f{\"u}hren kann. Die konventionellen Konzepte der Brennerentwicklung m{\"u}ssen daher f{\"u}r hochreaktive System neu gedacht werden, insbesondere f{\"u}r die Verbrennung von reinem Wasserstoff, der das obere Ende der Skala hochreaktiver Gasturbinentreibstoffe darstellt. Im Rahmen dieser Doktorarbeit wird der Einfluss verschiedener Ma{\ss}nahmen zur Vermeidung von Flammenr{\"u}ckschlag auf das nicht-reagierende und reagierende Str{\"o}mungsfeld experimentell untersucht. Dar{\"u}ber hinaus werden die Auswirkungen dieser {\"A}nderungen des Str{\"o}mungsfeldes auf die Flammenstabilisierung mit Hilfe moderner optischer Messtechnik gezeigt. Die daraus gewonnenen Erkenntnisse verm{\"o}gen die Beobachtungen der gemessenen Stabilit{\"a}tskarten zu erkl{\"a}ren. Durch die Identifikation von Indikatoren f{\"u}r Flammenr{\"u}ckschlag lassen sich au{\ss}erdem Voraussagen f{\"u}r die Stabilit{\"a}t jenseits des experimentell bestimmten Betriebsbereichs treffen. Im Rahmen der Untersuchungen stellte sich insbesondere das St{\"o}rungsfreie Einbringen des hohen Brennstoffimpulses als kritische Ma{\ss}nahme zur Wahrung von Flammenr{\"u}ckschlagsicherheit heraus. Weiterhin wurde gezeigt das verschiedene Ma{\ss}nahmen zur Vermeidung von Flammenr{\"u}ckschlag interagieren und teilweise interferieren. Es konnte jedoch gezeigt werden dass die vorgeschlagene Kombination der Ma{\ss}nahmen in der Brennergeometrie in der Lage ist Flammenr{\"u}ckschlag auf dem gesamten Betriebsbereich der Versuchsanlage zu verhindern und gleichzeitig ambitionierte Emissionsziele zu erf{\"u}llen.},

   abstract = {This paper presents a strategy to model the aerodynamic Gurney flap effect on two-dimensional airfoils and subsequently on the rotor blade performance of horizontal axis wind turbines.The first part consists of the parametric investigation of 26 airfoil polar data-sets, derived from different, but comparable, wind tunnel experiments. They are evaluated and processed in terms of the lift and drag increase caused by Gurney flaps in comparison to each Baseline configuration. Consequently, a model is developed, transforming Baseline- into Gurney flap polar data for varying flap-heights. The results of the emerging Gurney Flap Polar Calculator are validated against the experimental lift and drag curves.In the second part, the blade design of the NREL 5 MW Reference Turbine is modified by implementing polar data-sets of varying Gurney flap-heights, which are imported into the rotor simulation software QBlade. Thereupon, blade optimization strategies are examined regarding the two main Gurney flap applications on rotor blades: the retrofit and the design solution. The optimized retrofit solution on existing blades indicates power performance improvements, albeit at the expense of increasing structural loads. The optimized design solution on to-be-constructed blades, on the other hand, suggests chord-length reductions, while keeping the performance characteristics on a similar or even enhanced level.It is concluded that aerodynamic improvements are achieved by relatively small Gurney flap-heights, which are applied at specific blade positions.},

   abstract = {This paper shows that the interaction of an air stream (jet) coming from the outlet of a vehicle with the surrounding flow has an important impact on the pressure distribution in the outlet duct. Based on experimental investigations carried out in a wind tunnel it is shown that this interaction in most cases causes an additional counter pressure that has to be overcome by the acting fan. Depending on the parameter setting pressure differences in the order of several hundred Pascal can appear. Here, the most important parameter for this interaction turned out to be the momentum flux ratio of exhaust jet and cross-flow. This ratio is a result of the streams' fluid densities and velocities and is strongly affected by the near wall flow profile of the cross-flow upstream the outlet. Furthermore, the impact of geometry parameters such as the jet's exit shape is demonstrated.},

   abstract = {It is generally accepted that combustion of hydrogen and natural gas mixtures will become more prevalent in the near future, to allow for a further penetration of renewables in the European power generation system. The current work aims at the demonstration of the advantages of steam dilution, when highly reactive combustible mixtures are used in a swirl-stabilized combustor. To this end, high-pressure experiments have been conducted with a generic swirl-stabilized combustor featuring axial air injection to increase flashback safety. The experiments have been conducted with two fuel mixtures, at various pressure levels up to 9 bar and at four levels of steam dilution up to 25 \% steam-to-air mass flow ratio. Natural gas has been used as a reference fuel, whereas a mixture of natural gas and hydrogen (10 \% hydrogen by mass) represented an upper limit of hydrogen concentration in a natural gas network with hydrogen enrichment. The results of the emissions measurements are presented along with a reactor network model. The latter is applied as a means to qualitatively understand the chemical processes responsible for the observed emissions and their trends with increasing pressure and steam injection.},

For this reason, a test setup in the water towing tank of the Technical University of Berlin is being developed to adapt the physical boundary conditions including high Reynolds numbers for more accurate results and the possibility to investigate full length model train compositions. Advantages and limitations of these experiments in water are discussed and preliminary results are presented.},

   abstract = {The current paper investigates the nonlinear interaction of the flow field and the unsteady heat release rate and the role of swirl fluctuations. The test rig consists of a generic swirl-stabilized combustor fed with natural gas and equipped with a high-amplitude forcing device. The influence of the phase between axial and azimuthal velocity oscillations is assessed on the basis of the amplitude and phase relations between the velocity fluctuations at the inlet and the outlet of the burner. These relations are determined in the experiment with the Multi-Microphone-Method and a two component Laser-Doppler velocimeter. Particle image velocimetry and OH*-chemiluminescence measurements are conducted to study the interaction between the flow field and the flame. For several frequency regimes, characteristic properties of the forced flow field and flame are identified, and a strong amplitude dependence is observed. It is found that the convective time delay between the swirl generator and the flame has an important influence on swirl-number oscillations and the flame dynamics in the low-frequency regime. For mid and high frequencies, significant changes in the mean flow field and the mean flame position are identified for high forcing amplitudes. These affect the interaction between coherent structures and the flame and are suggested to be responsible for the saturation in the flame response at high forcing amplitudes.},

   abstract = {AbstractHumidified gas turbines and steam-injected gas turbines are promising technologies to lower the emissions and increase the efficiency and fuel flexibility of gas turbines. In the current study, the influence of steam-dilution on swirl-stabilized methane and hydrogen-fired flames is experimentally investigated at Reynolds numbers in the range of 22,000 to 32,000. Velocity fields and flame positions were measured using high-speed particle image velocimetry and OH* chemiluminescence. An extension of the quantitative light sheet technique was employed to estimate the temperature fields. The combined results reveal strong changes in the flame position, the velocity field, and the temperature field with increasing rates of steam dilution. In particular, three different flow and flame patterns are encountered: At dry conditions, a V-shaped flame stabilizes in a broad inner recirculation zone with low local turbulent kinetic energy; at moderate steam content, the flame changes into a trumpet-like shape; and at very high rates of steam-dilution, the flame detaches and shows an annular shape. The associated coherent flow structures are extracted from the PIV data employing proper orthogonal decomposition. The isothermal flow is dominated by a helical instability arising near the combustor inlet. This structure is completely suppressed for the dry flame and reappears for the heavily steam-diluted detached flame with similar shape and frequency as for the isothermal case. The flow field of the trumpet-like flame at intermediate to high steam dilution rates features a helical instability of lower frequency that is located further downstream than in the isothermal and very wet case. A conceptional explanation is presented that relates the suppression of the helical instability to the specific encountered temperature fields and flame shapes.},

   abstract = {The isothermal flow dynamics of a generic swirl burner are studied employing large eddy simulation (LES). A sensitivity analysis was conducted, considering different mesh sizes and subgrid-scale models and the results were compared to experimental data. It was found that the overall influence of the computational grid and the subgrid-scale model was neglectable and the simulations were in line with the experiments. A dominant frequency was found in the turbulent kinetic energy spectrum representing a coherent structure. Moreover, by applying the proper orthogonal decomposition (POD) this structure could be identified as a convective helical instability. This helical instability and can be represented by a pair of modes, and is assumed to be triggered by a precessing vortex core (PVC).},

   abstract = {The flow field of a swirl-stabilized burner for ultra-wet combustion is experimentally investigated by assessing the isothermal and the reacting flow. The ultra-wet combustion technique promises high cycle efficiency and low NOx emissions. Investigations of the non- reacting flow field are carried out in a water tunnel facility and the reacting flow is assessed in an atmospheric combustion test rig. Experiments were conducted at a theoretical swirl number of 0.7 and Reynolds numbers in the range of 22,000 to 32,000. Particle Image Velocimetry and OH-Chemiluminescence are employed to measure the flow velocities as well as the spatial distribution of heat release. The effect of steam addition up to levels of 30\% of the air mass flow is investigated for natural gas fuel and mixtures of natural gas and hydrogen. The results show a strong impact of steam addition on the flow field and the position of the reaction zone. In particular, three different flow patterns were found. Dry flames and hydrogen flames show a broad inner recirculation zone with very low local turbulent kinetic energy. At high rates of steam dilution, the flow fields show good agreement to the non-reacting flow field in water as well as in isothermal air. At intermediate to high steam dilution rates the flame shows a trumpet like shape. Several sudden changes of the flow field and flame shapes could be observed for various operating conditions.},

   number = {AIAA-2011-3585},
   pages = {13},
   abstract = {Reactor network models are widely used in studies of combustion kinetics. The mean residence time in the reactors is a crucial input for these models, however few attempts have been conceived so far to determine it accurately. In this study, the temporal and spatial distribution of a fluorescent tracer, injected as a short pulse, was measured using Highspeed planar laser-induced fluorescence (HS-PLIF), and Particle Image Velocimetry (PIV) was utilized for measuring the flow field. In a pulse experiment the tracer response in the combustor exit stream almost readily yields the residence time density function, which directly gives the mean residence time in the combustor. For a volume element within the combustor, the respective tracer response yields the time delay from the injection until the elements exit, but not its residence time, due to dispersion of the tracer input. The density function describes the deviation from the ideal transport in a plug flow and a perfectly mixed flow by considering two characteristic times: (1) a convective time delay \(\tau\)c, representing the time until the first detection of the tracer, and (2) a dispersive time delay \(\tau\)d, which characterizes the degree of dispersion upstream,and mixing within the respective volume element. A plug flow is solely described by \(\tau\)c, whereas a perfectly mixed flow is characterized only by \(\tau\)d. Time density functions were obtained at the injection holes, the combustion chamber inlet and outlet, as well as in an axicentric cross-section of the combustion chamber. The shape of density functions in the combustion chamber varies between that of an approx- imate plug flow and perfectly mixed flow, but mostly is represented by a superposition of the two. The distribution of \(\tau\)c indicates the path of the tracer through the combus- tor. By means of the \(\tau\)d distribution, zones of similar mixing characteristics are identified. The external recirculation zone (ERZ) is among these; however, only part of the internal recirculation zone (IRZ), that is less effected by entrainment from the jet, exhibits these similar mixing characteristics. Based on the experimental findings, a semi-empirical re- actor network model was developed applying an extended tanks-in-series approach. The model agrees very well with the measured time density functions. The transfer functions of the recirculation zones are used to determine the actual mean residence time in these zones. The mean residence time in the IRZ yields 21\% of the total combustor residence time and 25\% in the ERZ.},
