Contribution à la modélisation eulérienne unifiée de l'injection : de la zone dense au spray polydispersé

Autor: Essadki, Mohamed

L’injection directe à haute pression du carburant dans les moteurs à combustion interne permet une atomisation compacte et efficace. Dans ce contexte, la simulation numérique de l’injection est devenue un outil fondamental pour la conception i
