Publikováno v: Physics of Fluids. 29:056101

The propagation of two-dimensional cellular gaseous detonation bounded by an inert layer is examined via computational simulations. The analysis is based on the high-order integration of the reactive Euler equations with a one-step irreversible react

Publikováno v: Autre. ISAE-ENSMA Ecole Nationale Supérieure de Mécanique et d'Aérotechique-Poitiers, 2017. Français. ⟨NNT : 2017ESMA0017⟩

This dissertation is devoted to the numerical study of detonation waves, and more specifically to the dynamics of detonations bounded by an inert gaseous layer. This configuration is similar to the flow field within the rotating detonation engines, i
