Abstract
Flame/vortex interaction is a topic of major importance for the understanding of fundamental combustion processes involving the coupling between fluid dynamics and combustion, such as turbulent combustion and combustion instability. Considering the canonical problem of the head¿on interaction of a vortex ring and a diffusion flame, the various interaction regimes that may arise have been studied theoretically, numerically, and experimentally by several authors, leading to non¿premixed flame/vortex interaction diagrams which summarize the current knowledge in the field. In previous investigations, the authors developed a simplified mathematical model to describe the non¿premixed flame/vortex interaction process and used order of magnitude estimates to characterize the regime of strong vortices interacting with robust flames. The analysis led to an extended combustion diagram characterizing the regimes of interaction of nonpremixed flames and strong vortices, of particular relevance for the understanding of H2¿Air diffusion flames/vortex interactions. The aim of this work is to carry out realistic numerical simulations of the interaction of diluted H2¿Air diffusion flames with strong vortices in order to assess the validity of the proposed combustion diagram as well as to illustrate the characteristics of the different interaction regimes.
