 Abstract:

Over the last decade, non-thermal plasmas have shown good potential for applications in gas turbines and aero-engines. More specifically they were successfully used to increase the flammability range, increase the burning velocity and control thermo-acoustic instabilities in several configurations. However, the vast majority of these studies were performed at atmospheric pressure. Therefore, are these non-thermal plasma a realistic option for flame actuation in gas turbines, for which high-pressure turbulent flows are the norm? In this colloquium, after introducing the different combustion processes and explaining how we can achieve plasma-assisted combustion, I will present some of the recent results we have obtained in my group, on high-pressure turbulent flame actuation by nanosecond repetitively pulsed plasma discharges.
