“…Most of previous works have used option 1, Y c and density equation [12,14] or option 2.1, species transport equations and tabulated reaction rates [20]. Because of their target applications involving fewer input data within relatively small variations (in comparison with engine operating points), their number of tabulated points were not strictly limited.…”

Résumé -Développement d'une tabulation FPI pour la prise en compte de la chimie complexe dans la simulation 3D moteurs -L'objectif de cette étude est d'utiliser une tabulation de la chimie de type FPI (Flame Prolongation of ILDM) pour la simulation 3D de la combustion dans les moteurs. La première difficulté a été d'adapter la méthode à des codes compressibles tout en se limitant à des tailles de tables raisonnables. Pour satisfaire ces contraintes, une nouvelle formulation a été proposée. Elle permet de garder une structure de code basée sur le transport de quelques espèces chimiques tout en assurant la cohérence de l'évolution du système grâce à une équation pour l'avancement de la réaction. Le terme source chimique impliqué dans cette dernière est directement extrait de la tabulation. L'approche retenue permet également d'appliquer la modélisation FPI à des problématiques moteur comme l'utilisation de carburants complexes caractérisés par des chimies détaillées très lourdes ou la combustion fortement diluée. Le modèle proposé, introduit dans le code de simulation moteur IFP-C3D, a été validé sur des configurations homogènes à volume constant et à volume variable contrôlé. Enfin, le modèle complet a été appliqué avec succès à un cas moteur Diesel à injection directe.

“…In the literature, there are only few LES studies of hydrogen auto-ignition, using the probability density function (PDF) as a sub-grid scale model [3,4], or tabulated chemistry [5]. In [3,4], the ignition length was well reproduced and it was also demonstrated that flashback occurs at high co-flow temperatures.…”

“…In that way, homogeneous turbulence is obtained. The chosen length and time scales are 4.5mm and 1ms, with turbulence intensity 12.5% [1,5]. A second option is to apply random white noise, although this is known not to describe real turbulence adequately.…”

“…Numerical investigations of the case [9], reported so far, were undertaken mainly with the transported PDF with detailed combustion model [16,17], or tabulated chemistry [18] in combination with LES. In [19], the CMC model has been applied in a RANS context but the 'random spots' regime was not reproduced: in all cases studied an attached flame was formed.…”

DOI: 10.1007/s10494-013-9443-2 Noname manuscript No. (will be inserted by the editor) LES-CMC simulations of different auto-ignition regimes of hydrogen in a hot turbulent air co-flowReceived: date / Accepted: date Abstract Large-Eddy Simulation (LES) results in combination with first-order Conditional Moment Closure (CMC) are presented for a hydrogen jet, diluted with nitrogen, issued into a turbulent co-flowing hot air stream. The fuel mixes with the co-flow air, ignites and forms a lifted-like flame. Global trends in the experimental observations are in general well reproduced: the auto-ignition length decreases with increase in co-flow temperature and increases with increase in co-flow velocity. In the experiments, the co-flow temperature was varied, so that different auto-ignition regimes, including low Damköhler number situations, were obtained (no ignition, random spots, flashback and lifted flame). All regimes are recovered in the simulations. Auto-ignition is found to be the stabilizing mechanism. The impact of different detailed chemistry mechanisms on the auto-ignition predictions is discussed. With increasing air temperature, the differences between the mechanisms considered diminish. The evolution of temperature, H 2 O, H, HO 2 and OH from inert to burning conditions is discussed in mixture fraction space.
