“…Compared to experiment, fluctuating velocity profiles are also well captured in shape, but are underestimated by the simulation. This was also observed in [47,50] and is due to the missing RUM, that represents a significant (Fig. 18).…”

“…In these equations, the momentum and heat phase exchange source terms are split in two parts : It has been shown in [47] that the resulting set of equations Eqs. 8 to 11 leads to solutions similar to Lagrangian solutions in the case of a two-phase turbulent channel flow.…”

“…However the modelling of these terms as proposed for example in [47,49,50] is not yet satisfactory and it is still an open and difficult question. In [47,50] it has been shown that in a configuration representative of industrial flows, the RUM is not essential to capture the mean fields (velocity and mass flux) of the liquid phase, but only influences the particle turbulent agitation. It has been therefore omitted in the applications presented later in the paper.…”

An extension of the Large Eddy Simulation (LES) technique to two-phase reacting flows, required to capture and predict the behavior of industrial burners, is presented.While most efforts reported in the literature to construct LES solvers for two-phase flow focus on Euler-Lagrange formulation, the present work explores a different solution ('two-fluid' approach) where an Eulerian formulation is used for the liquid phase and coupled with the LES solver of the gas phase. The equations used for each phase and the coupling terms are presented before describing validation in two simple cases which gather some of the specificities of real combustion chamber: (1) a one-dimensional laminar JP10/air flame and (2) a non-reacting swirled flow where solid particles disperse [1]. After these validations, the LES tool is applied to a realistic aircraft combustion chamber to study both a steady flame regime and an ignition sequence by a spark. Results bring new insights into the physics of these complex flames and demonstrate the capabilities of two-fluid LES.

“…The monodisperse equation system used in this study is a simplification of the model by Février et al [5]. There is no account for the random uncorrelated motion [15]. The resulting model leads to equations for the droplet number density, the liquid volume fraction, the mesoscopic velocity and the mesoscopic enthalpy.…”

Large-Eddy Simulations (LES) of an evaporating two-phase flow in an experimental burner are performed using two different solvers, CDP from CTR-Stanford and AVBP from CERFACS, on the same grid and for the same operating conditions. Results are evaluated by comparison with experimental data. The CDP code uses a Lagrangian particle tracking method (EL) while the code AVBP can be coupled either with a mesoscopic Eulerian approach (EE) or with a Lagrangian method (EL). After a validation of the purely gaseous flow in the burner, liquid-phase dynamics, droplet dispersion and fuel evaporation are qualitatively and quantitatively evaluated for three twophase flow simulations. They are respectively referred as: CDP-EL, AVBP-EE and AVBP-EL. The results of the three simulations show reasonable agreement with experiments for the two-phase flow case. RésuméSimulations eulériennes et lagrangiennes aux grandeséchelles d'unécoulement diphasiqueévaporant Les simulations aux grandeséchelles (SGE) de l'écoulement diphasiqueévaporant dans un brûleur expérimental sont réalisées avec deux codes numériques différents, CDP du CTR-Stanford et AVBP du CERFACS, sur le même maillage et pour les mêmes points de fonctionnement. Les résultats obtenus sont validés par comparaison avec des données expérimentales. Le code CDP peutêtre coupléà une méthode de suivi Lagrangien de la phase liquide (EL). Le code AVBP peut soitêtre coupléà une méthode mésoscopique Eulérienne (EE), soità une méthode de suivi Lagrangien (EL). Après validation de l'écoulement purement gazeux dans le brûleur, la dynamique de la phase liquide, la dispersion et l'évaporation du carburant sontévaluées qualitativement et quantitativement pour trois simulations diphasiques dénotées respectivement : CDP-EL, AVBP-EE et AVBP-EL. Les résultats obtenus par les trois simulations sont en accord raisonable avec l'expérience pour l'écoulement diphasique.
