A moment method for polydisperse sprays
Comptes Rendus. Mathématique, Volume 347 (2009) no. 11-12, pp. 691-696.

This Note outlines a new moment method to solve the kinetic spray equation, which is the basic mathematical model used to predict the behaviour of polydisperse sprays. The method was successfully applied to the test-cases of spray-wall impingement and crossing of two spray jets that were affected by the Stokes drag force. Lagrangian computations of the same test-cases were used as reference solutions.

Dans cette Note, nous proposons une nouvelle méthode de moments pour la modélisation des sprays, permettant de traiter des situations de fort déséquilibre, dans lesquelles la fonction de distribution caractérisant le brouillard est localement multimodale vis à vis de la taille ou de la vitesse des gouttes. Cette méthode a été appliquée avec succès aux cas de l'éclaboussement d'un spray sur une paroi et du croisement de deux jets de granulométries différentes.
