Texto completoIgnition constitutes a critical phase in many combustion applications and specifically those related to aerospace propulsion. One of the current challenges has been to develop large eddy simulations of this transient phenomenon in realistic configurations like those found in aeroengines.In this respect, the pioneering work of Boileau et a. (2008) indicated that complete calculations of this process in a full annular combustor geometry could be carried out and that they provided first hand information on the light-round process.It was however important to see if the simulation can match well controlled experimental data. This is accomplished in the present work which uses a novel experimental device named MICCA. The thesis describes the experimental set of data,the calculation methodology and its validation in a single burner configuration,results of large eddy simulation of the full light round process, a detailed analysis of the numerical results and an attempt to build a simplified model of the process based on macroscopic balance equations

Texto completoThese last decades have seen many innovations in the field of combustion to reduce fuel consumption and pollutant emissions. New types of injector, for example LPP - Lean Premixed Prevaporized, have then been developed to reduce the fuel / air ratio and aim to pre-vaporize the fuel upstream of the combustion in order to mix it better with the air coming from the compressor. Unfortunately this architecture makes annular chambers more sensitive to unsteady phenomena which disturb the functioning of the system, increase the heat flows towards the walls of the chamber, induce vibrations of structures, cause cyclic fatigue of mechanical parts and in extreme cases lead to irreversible damage. The objective of this thesis is to continue the effort undertaken at the EM2C laboratory on this topic and more particularly on the dynamics of combustion in annular chambers comprising a set of injectors. The thesis concerns more particularly the case where the injection of the fuel takes place in liquid form. This configuration reproduces, in idealized form, what can be found in practice in aeronautical engines. It is also a configuration studied at the fundamental level. The chamber, known as MICCA-Spray, is equipped with 16 swirled injectors that can be powered by liquid or gaseous fuel, thus enabling two-phase or fully premixed combustion. The system has quartz walls giving optical access to the flame zone. It is also equipped with a set of diagnostics such as microphones, photomultipliers and high-speed imaging systems

Texto completoThe emphasis on many-particles radioactive decays requires a tracking detector like a Time Projection Chamber (TPC), which operating point can be set in accordance with the nucleides analyzed. The electrical model of such a detector reveals that, depending on its operating conditions and the nature of elements under study, the signals dynamic range can be up to more than five orders of magnitude. Consequently, an application specific processing system has to be designed. To meet the requirements of the experimental equipment, this system muste be integrated and its functional architecture muste be similar to the one of the prototype presented. The topology of the input stage of the protoype narrows the dynamics of the processing. The solution suffested to solve this problem consists in substituting this stage by a second generation current conveyor (CCII) with multiple outputs. The study of its linearity leads to predict the highest signal amplitude that it's able to process. A dynamic range greater than 1. 10(5) obtained in simulation with adapted filters. Optimization of this conveyor and filters coukd lead to extend even more this dynamic range

Texto completoCell adhesion receptors of the classical cadherin family are involved in Ca2+-dependent homophilic interactions. In order to dissect the molecular mechanisms of cadherin-based cellcell adhesion, this Ph.D. thesis describes a comparative dynamic study of interactions between cadherins E- & -11, chosen as classical type I and II cadherins prototypes respectively. Modifications of particular residues in the E-cadherin adhesive interface showed that the ?-strand exchange with its Trp2 had a prominent feature; for type II cadherins, a different mechanism was described involving a larger domain swapping. We then developed a new protocol for immobilizing proteins in an orientated and covalent manner on surfaces. These interactions regulate signalization pathways in various biological processes. Studies describing Stat3 activation through direct cadherin engagement are reviewed

Texto completoDespite the notoriety of Gabriel Fauré’s musical style, the particular style of his chamber music still remains difficult to comprehend by analysis. Formal construction is a real subject of question. While some analysts try to attest to his originality by examining how it departs from tradition, others offer analyses of the dynamic characteristic of its themes, whose continuous development leads to the realization of large form. The latter have so far relied on a limited corpus of works. This thesis proposes to expand the corpus to the five large chamber works for strings and piano - two Quartets op. 15 and 45, two Quintets op. 89 and 115 and the Trio op. 120 in order to define the “formal dynamics.” After the study of testimonies from the composer's time that highlights the formal originality in his work, the subsequent analysis deals with the internal arrangement of themes and the realization of large form from the study of scores. I conduct my analysis with the help of graphic representation created by a computer software that can visualize the enveloping dynamic and identify climaxes. By revealing the contents of this process, this thesis helps to better reflect the very personal style of Fauré and the way in which he creates music that gives the impression of continuous progression and development extending to the end of the work

Texto completoSome interactions beetween membrane molecules have a decisive role in immune system function, especially during leucocyte recrutement on endothelial surface, and during T cell recognition. Studying those molecular interactions implies to mesure kitenic parameters with surfaces bonded molecules, and effect of moleculat environment and forces applied on bonds. The laminar flow chamber is a technic that permits such measurements, that was automatized and developped during this work. An adhesion model showed the influence of a model glycocalyx on single bonds. Influence of a power law of time on an antigene-antibody bond formation was shown. Half-life of several TCR-pMHC bonds was measured using surface-bonded molecules, showing effects of force and available time for bond formation. The technical improvements to flow chamber done were applied to developpement of a diagnostic test for Leucocyte Adhesion Deficiencies, and to preliminary work on a susceptibility test for atherosclerosis

Texto completoThe studied facility concerns a set of "outlet guide vane, diffuser, combustion chamber". This should realize a good recovery of static pressure under different feeding and bleed conditions. In deed, the reduction of the axial dimensions and the decrease of losses are a major issue in the design of new engines, and the improvement of performance of such devices can be achieved only through an understanding of phenomena occurring in these elements. It is also essential to take into account their interactions. This experimental study offers the possibility to perform detailed and comprehensive measures of the influence of upstream and downstream conditions on a combustor diffuser by testing modular configurations with more and more complex option settings (bypass flow). Some tested configurations can generate incident flows with several levels of turbulence. The isovalue maps of aerodynamic magnitudes and parietal pressure survey can be obtained between the different sections for all tested configurations. Parietal visualizations are possible within the diffuser. This study will also review the results gained with the pressure probe mainly used, and corrections to the flow angles will be proposed on the basis of laser measurements. These stereoscopic PIV measurements are performed in a configuration to overcome the problems of optical access and will be validated by the establishment of a criterion based on continuity

Texto completoIt appears tempting to combine the less polluting combustion of LPG with the energy performances of a direct injection spark-ignition engine. To this aim the study of high pressure injection of a liquid GPL jet, directly inside the combustion chamber of an engine was performed in two ways: Experimental studies : one with fast cinematography and another with the method of Doppler phases in an one-cylinder " transparent " engine for various conditions of injection and without combustion. They respectively deliver empirical laws for the jet development and some informations about size and speed of the droplets of LPG. A modeling of the jet could then be made on the basis of a turbulent and deviated jet the parameters of which could be adjusted using results of the preceding experimental study

Texto completoVolatile Organic Compounds (VOC) play a key role in atmospheric chemistry influencing climate and air quality. Vegetation is the main source of VOC, accounting for 90% of biogenic emissions (BVOC). Agricultural crops in Europe are estimated to contribute 27% of total BVOC emissions but remain poorly studied. In this work, we study the exchange of BVOC by wheat, rapeseed and maize, the main agricultural species in France in terms of cultivated area. The fluxes were measured in the field at the plant level with dynamic automated chambers coupled to a PTR-Qi-Tof-MS spectrometer. Fluxes of up to 997 compounds could be measured with this highly sensitive instrument. Chapter 1 presents a review of BVOC emission mechanisms, flux measurement methods, experimental results on BVOC exchanges in agricultural systems, and mathematical models of emissions. Chapter 2 describes the measurement site and the experimental setup. Chapter 3 presents BVOC fluxes measured during one week for each species. Emissions were dominated by methanol (55-85% of total emissions) followed by acetone and acetaldehyde. The 10 most emitted compounds excluding methanol accounted for more than 50% of total emissions and the 100 most emitted compounds accounted for more than 90%. The measured fluxes showed little intra-species variation but large inter-species variations with total net fluxes of 0.11±0.02 µg_BVOC g_DW^(-1) h^(-1) for maize, 1.5±0.7 µg_COVB g_MS^(-1) h^(-1) for wheat, and 9.1±2.4 µg_COVB g_MS^(-1) h^(-1) for rapeseed. Finally, standard emission factors for isoprene and monoterpenes were evaluated for each species, constituting the first known estimates for rapeseed. Chapter 4 examines the influence of developmental stages, and particularly of senescence, on BVOC emissions from wheat. We report a doubling of total emissions during senescence compared to maturation, with, in particular, an increase in the contribution of acetaldehyde (1.6% of total emissions during maturation and 9.7% during senescence) and acetic acid (0.7% during maturation and 2.7% during senescence). In Chapter 5 the main parameters of the MEGAN 2.1 model are estimated for the three species and the fluxes of six main compounds measured for rapeseed at the plant level by the dynamic chambers are compared with measurements by Eddy Covariance at the ecosystem level in order to evaluate the representativeness of chamber measurement. This work shows the heterogeneity of BVOC exchanges by agricultural plants and the data generated should contribute to the improvement of emission models

Texto completoBuilt for intermediate energy heavy ions nuclear physics, the M. E. Ω detector uses various and complementary detection methods: ionization chamber, parallel plate avalanche counter, plastic scintillators. With these techniques, velocity, energy, mass and charge of nuclei were measured over wide range. From the detailed theoretical study of each method, limitations and perturbation causes are deduced. The solutions used for optimizing the detector, and the main results are exposed. The internal sectorisation of the detector, which permits a modulation in counting rate and electronical adjustments, has been revealed to be very suitable for heavy ions intermediate energy physics. Results of the first experiment realized with M. E. Ω (Ar + Ag at 35 MeV/u) are commented

Texto completoThe optimisation of turbocraft combustion chamber cooling systems is nowadays one of the main challenges engineers have to deal with. The current work presents an experimental aerodynamic study of the multiholed cooling technique on a 10:1 scale flat plate. A great deal of attention has been paid during the development of the test rig to obtain clearly identified boundary conditions that are necessary to perform a relevant comparison between the present experimental results and related numerical simulations. LDA velocity measurements allowed to investigate the blowing rate and Reynolds number influence on the film cooling evolution in the middle and downstream the perforated zone. The kidney shape and the contra rotating pair vortex are investigated and then friction velocity and friction coefficient are experimentally estimated in the multiperforated region. Depth jet penetrations and film cooling thickness correlations are elaborated. Finally, all experimental results will be used to evaluate and validate future codes needed to simulate flows over multiperforated walls

Texto completoThe increasingly stringent environmental standards imposed on air transport are pushing manufacturers to upgrade the existing combustion chambers. To reduce pollutant emissions, lean, premixed and pre-evaporated combustion is an interesting alternative. This technology, however, can lead to a less stable flame and can generate combustion instabilities harmful to the engine. In order to improve control over such combustion systems, multi-stage burners provide additional flexibility through the distribution of fuel between the different injection systems, and thus influence the position of the flame or the burning regime. The BIMER experimental bench has been specially developed in the EM2C laboratory to study this solution. It has been designed to be representative of a real aviation engine and to reproduce its essential characteristics : a two-stage configuration, preheated air and liquid fuel are used. It nevertheless operates at atmospheric pressure and develops a high thermal power at the laboratory scale. The burner consists of two radial swirlers : the pilot stage in which the liquid fuel is injected in the form of a hollow cone, and the multipoint stage where the mixture of fuel and air is favored by a multipoint injection, thanks to ten jets of fuel injected transversely to the air flow. Experimental studies have shown the key role of the fuel distribution, and without modifying the power developed, the existence of a hysteresis cycle : several archetypes of flames can be stabilized, depending on the flow, spray or history of the flame. The objective of this thesis is to complete the experimental data and understanding of poor, premixed and pre-vaporized flame stabilization processes in staged burner using two-phase reactive large-eddy simulations. This numerical approach is applied to the BIMER bench with the AVBP code. Successive simulations, ranging from pure pilot injection to purely multipoint injection, and vice versa, have made it possible to trace the hysteresis cycle observed experimentally. An original tri-stable operating point was encountered numerically for fuel injection cases in the pilot stage alone, with three distinct flame shapes being observed for this single injection condition. The comparison to the experimental results for the operating points for which validation data are available shows a good agreement between the calculation and the experiment for different stages. An original analysis in the composition space shows the combustion regimes observed in these three cases, confirming the different stabilization scenarios. The two transitions of flame shapes observed experimentally are finally presented and analyzed

Texto completoOur study aims at improving the understanding of how a detonation may continuously rotate. It is focused on rotation modes in an annular chamber with constant or linearly increasing normal section. The functioning principle is based on the continuous injection of fresh reactive gases so as to regenerate a reactive layer ahead of the detonation front and maintain sufficient conditions for detonation propagation. The main incentive of the work is the development of propulsive devices that use detonation as the combustion mode (Rotating Detonation Engine, RDE). We have designed and built an experimental test bench of which the main part is an annular chamber with inner diameter 50 mm length 90 mm, and thickness 5 or 10 mm. The chamber can be equipped with cylindrical or conical kernels with lengths ranging between 12 mm and 90 mm and, for the conical kernels, with the apex half-angles ranging between 0± and 14.6±. The fuel is ethylene and the oxidizer is a mixture of oxygen and nitrogen, and they are injected separately in the chamber. We have considered several nitrogen concentrations so as to vary the reactive mixture detonability. The characterizations of the detonation regimes, velocities and pressures are based upon the analyses of signals from pressure transducers and of direct light visualizations from high-speed cameras. Our experimental results detail the ignition phase, the combustion modes and their stability. We have carried out experiments with several detonabilities, mass-flow rates and kernel geometries. Our main finding is that modifying the kernel geometry, specifically decreasing the kernel length and increasing its conicity (the apex half-angle) significantly improve detonation velocities and pressures, unlike the first two parameters that have much lesser influences, in our conditions. We have conducted a numerical analysis that suggests that dilution and heating of the fresh gases by detonation products explain the measured deficits of pressure and velocity. We have presented a calculation of thermodynamic efficiency which, contrary to former modeling includes a more realistic structure of rotating detonation.We have proposed a calculation of detonation-front height for the rotation modes and the chamber geometries in this work. Our study thus demonstrates the interest in further research work on inner geometry of rotating-detonation chambers and on phenomena that may be responsible for efficiency losses

Texto completoChemical species densities like H₂O, CO₂, CO, K, HCl and thermodynamic data like pressure and temperature are keys parameters to understand combustion. Measurements of these parameters are great help to validate or complement numerical simulations aiming at improving engine design and efficiency. The current thesis presents the development of an optical characterization method leading to two dimensional maps of chemical densities, pressure and temperature in combustion flames. This method consists to acquire absorption spectra at different positions and angles around the reactive flow. The spectral inversion of these data can be used to recover quantitatively chemical densities, pressure and temperature. In this thesis, we have chosen to combine this spectral inversion with a tomographic algorithm in order to obtain results with improved spatial resolution. The developed method is called Tunable Diode Laser Absorption Tomography (TDLAT).Two research directions have been followed during the thesis. The first consisted to develop several absorption spectrometers associated with a mechanical scanning device of the flame. In a second time, we have searched to develop a non-linear tomographic algorithm in order to process absorption spectra series in order to obtain spatial resolution. The main results obtained in simulations have led to an optimization of the tomographic algorithm in order to adapt its functioning to measurements configurations characteristics of combustion benches. The main measurements results have been acquired in a laboratory flame and in a solid propellant combustion bench
Chatelier, Adrien. "Modeling questions for numerical simulations of aeronautical combustors". Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLC061/document.
Texto completoThe design of aeronautical combustion chambers requires a precise balance between the different physical phenomena involved, such as flame-turbulence interaction, heat losses, flame dynamics or fuel evaporation and mixing. Numerous numerical tools exist in the literature to predict these kinds of turbulent reacting flows. The unsteady turbulence models, for example LES (Large Eddy Simulation), represent an excellent compromise for the prediction of the mixing in realistic configurations. The tabulated chemistry approach is an attractive trade-off between computation cost and accuracy for predicting the structure of flames. In this thesis, advanced turbulence and tabulated chemistry models are applied to complex configurations in order to assess their ability to predict the structure of turbulent flames. The prediction of the FDF (Flame Describing Function) by the F-TACLES (Filtered TAbulated Chemistry for Large Eddy Simulations) model is compared to experimental data for a non-adiabatic premixed swirled flame. The FDF is well predicted for a wide range of frequencies and two velocity fluctuation levels. The origin of the discrepancies is analyzed. The first application of the F-TACLES model in a two-phase burner is proposed. The chosen burner is the KIAI spray jet flame, recently studied at CORIA. A detailed comparison with the experiments is performed and shows that F-TACLES is able to predict the correct flame shape. The ZDES (Zonal Detached Eddy Simulation) model is studied in a realistic aeronautical injector, the TLC configuration. In cold conditions, the ZDES is validated against velocity measurements and compared to LES results. In reacting conditions, the prediction of temperature profiles in the combustion chamber is greatly improved in the ZDES
