With the large increase in available computational resources, large-eddy simulation (LES) of industrial configurations has become an efficient and tractable alternative to traditional multiphase turbulence models. Many applications involve a liquid or solid disperse phase carried by a gas phase (e.g., fuel injection in automotive or aeronautical engines,… (More)

A major issue for the simulation of two-phase flows in engines concerns the modeling of the liquid disperse phase, either in the Lagrangian or the Eulerian approach. In the perspective of massively parallel computing, the Eulerian approach seems to be more suitable, as it uses the same algorithm as the gaseous phase solver. However taking into account the… (More)

A new Eulerian model is derived for polydisperse moderately-inertial sprays with coalescence: an Anisotropic Gaussian Velocity Closure conserves all the second order moments to render the spatial structure of the spray after Droplet Trajectory Crossing. Polydispersity is treated with a high order in size Multi-Fluid method where coalescence terms are… (More)

The accurate simulation of disperse two-phase flows, where a discrete particulate condensed phase is transported by a carrier gas, is crucial for many applications; Eulerian approaches are well suited for high performance computations of such flows. However when the particles from the disperse phase have a significant inertia compared to the time scales of… (More)

In this work, we are interested in the modeling of spray polydispersion in size as well as size-velocity correlations, which may greatly influence the evaporation and the dynamics of the disperse phase. Vié et al. 2011 proposed a new model called Coupled Size-Velocity Moment method (CSVM), which handles the polydispersion using the NDF reconstruction… (More)

The flame-vortex interaction is a canonical configuration for theoretical understanding of the combustion mechanisms in turbulent flows (Poinsot et al. 1991). Specifically, under the flamelet hypothesis, the turbulent flame front is seen as a collection of onedimensional flames that are stretched and deformed by vortices (Peters 1984). Indeed, the effect of… (More)
