Lechner, Valentin. "Experimental study of LOX/CH4 flames in rocket engines." Electronic Thesis or Diss., université Paris-Saclay, 2024. http://www.theses.fr/2024UPAST040.
Using methane as a fuel in rocket engines would have many advantages but the combustion with pure oxygen at high pressure remains poorly understood. From a thermodynamic point of view, methane and oxygen share very similar critical point values, making it challenging to predict propellant mixing, flame anchoring, stability and structure. Moreover, when methane is injected in excess, aerosols can be produced, which can clog the lines, damage the turbine, and reduce the efficiency.Therefore, a thorough update of the knowledge of LOX/CH4 combustion is necessary. These challenges are tackled within the consortium composed of EM2C laboratory, ONERA, CNES, and ArianeGroup. Two test campaigns are carried out at the MASCOTTE facility from ONERA, aiming to study three central topics: the flame structure, wall heat transfers, and aerosol production. To this end, various experimental diagnostics are implemented simultaneously during high-pressure hot-fire tests.Various imaging diagnostics are implemented to analyze the flame structure and the dense liquid jets. Despite the acquisition difficulties encountered in these extreme conditions, the analyses reveal a complex flame structure. In the subcritical regime, atomization and evaporation mechanisms dominate. The flame is much more opened and longer than at higher pressures, where diffusive mixing mechanisms prevail. Characterizing flame anchoring remains a challenge. A water ice ring surrounding, and masking, the flame foot has been identified. Formation mechanisms are proposed, and a growth/destruction temporal cycle is highlighted. Its presence strongly affects flame visualizations, and may lead to misinterpretations of its topology.Laser-induced phosphorescence (LIP) is implemented for the first time at MASCOTTE. Various LIP methods exist, but they are not well suited to the MASCOTTE conditions: wide temperature range, thermal transients, and two-phase flow environment favoring laser absorption/diffusion. Therefore, a specific method, the Full Spectrum Fitting method (FSF method), has been developed. It exploits the spectral dependence on temperature, enabling instantaneous measurements from 100 to 900 K with a precision of 17 K, with no dependence on the laser excitation energy. A detailed data analysis highlights the predominant wall heat transfer modes, studies the influence of the operating points, and compares the experimental data with a wall heat transfer model, which is particularly well suited for deducing the convective properties of the flow.Three diagnostics are used to characterize aerosols. An intrusive probe samples particles and burnt gases downstream of the flame. The particles are sampled on TEM grids and analyzed by Transmission Electron Microscopy. Detailed images of the aerosol morphology reveal that the particles are soot. Combustion products are analyzed by gas chromatography. This makes it possible to identify soot precursor molecules such as benzene and acetylene. Soot are quantified temporally by laser extinction. A dedicated post-processing method is developed and various hypotheses are discussed to explain the spatial variations of the soot production downstream of the flame

Salusbury, Sean. "Premixed methane stagnation flames with oxygen enrichment." Thesis, McGill University, 2010. http://digitool.Library.McGill.CA:80/R/?func=dbin-jump-full&object_id=87008.
The experimental apparatus that is used to gather data in this study is a stagnation flame burner. Particle image velocimetry, a laser-based flow visualization technique, is used to measure velocity in both the axial and radial directions. The results are analyzed first to confirm the validity of the one-dimensional, axisymmetric model commonly used to describe impinging-jet flow. Experimental results are found to have good agreement with theoretical approximations and numerical models. Tests are then conducted to reproduce previously published data for methane-air flames at lean, stoichiometric and rich conditions in order to prove the reliability of the experimental apparatus. There is agreement between published data and the new experimental results.
Experiments with oxygen enrichment are then conducted at equivalence ratios not normally within the flammability limits of methane-air mixtures, from the very lean, phi = 0.55, to the very rich, phi = 1.45. Results show marked disagreement between model and experiment at equivalence ratios far from stoichiometric. These experimental data will allow the chemical kinetic model for premixed methane combustion to be improved -- by correcting divergence in the model at very lean and very rich conditions, the model should be improved appreciably over the narrower range of equivalence ratios typically seen in methane-air combustion.
La cinétique chimique est la science de la modélisation des étapes d'une réaction chimique au niveau moléculaire. Ce mémoire s'interesse aux réactions chimique qui se produisent durant la combustion. Les modèles cinétique présentement acceptés sont en besoin d'amélioration et d'autres enplus, il existe plusieurs réactions qui n'ont aucun modèle. Pour mieux développer les modèles et pour en créer des nouveaux, il fault rassembler assez de données expérimentales pour produire une base solide sur laquelle des modèles de plus en plus compliqués peuvent etre construits.
Pour générer des données, cette étude utilise un appareil expérimental avec une géométrie de point d'arrêt, dans laquelle une flamme aplatie peut exister. Les vitesses dans la direction axiale et radiale sont mesurées par la vélocimétire image-particule, une technique à base de laser. Les résultats sont d'abord analisés pour vérifier que le modèle unidimensionnel est valide. Une bonne concordance est observée entre la théorie et les résultats et entre les modèles numériques et les résultats. Subséquemment, des expériences sont effectuées pour reproduire des données déjà publiées pour le méthane et l'air aux rapports d'équivalence oxydants, stoechiométriques et réducteurs, afin de prouver la fiabilité de l'appareil expérimental. Il ya une bonne concordance entre les données publiées et les résultats expérimentaux.
Des expériences dans lequelles l'air est enrichi avec de l'oxygène sont effectuées à des rapports d'équivalence de phi = 0.55 juste qu'à phi = 1.45; ces rapports d'équivalence ne sont normalement pas dans les limites d'inflammabilité des mélanges de méthane-air. Ici, les résultats montrent un désaccord marqué entre le modèle et les expériences pour les rapports d'équivalence très loin de phi = 1.0. Les données permettent le modèle cinétique chimique pour la combustion du méthane prémélangée d'être amélioré. En corrigeant les divergences entre le modèle et les resultats experimentales pour rapports d'équivalence très oxydants et très réducteurs, le modèle sera amélioré pour rapports d'équivalences généralement vus dans la combusiton de méthane dans l'air.
