Numerical simulation of sprays can potentially be used for assessing the performance and variability of engines. But today’s simulations only provide average quantities, after calibration. Spray injection can be thought of as a multiscale problem w

High fidelity modeling and simulation of moderately dense sprays at relatively low cost is still a major challenge for many applications. For that purpose, we introduce a new multi-fluid model based on a two-size moment formalism in sections, which a

International audience; Solid rocket motor flows depend strongly on alumina granulometry, which spreads up with coalescence. Solving droplet sizes in unsteady flows is a modeling and numerical challenge, specially when high loadings generate retrocou
