Prediction and control of combustion instabilities in real engines
Thierry Poinsot,Thierry Poinsot +1 more
TL;DR: In this paper, the authors present recent progress in the field of thermoacoustic combustion instabilities in propulsion engines such as rockets or gas turbines, and show that LES is not sufficient and that theory, even in these complex systems, plays a major role to understand both experimental and LES results and to identify mitigation techniques.

Dynamics of Swirling Flames
TL;DR: In this paper, a discussion of the swirl number, a parameter that plays a central role in the definition of the flow structure and its response to incoming disturbances, is presented, where the interaction between the swirler response and incoming acoustic perturbations generates a vorticity wave convected by the flow.
