Lean combustion is used in order to maintain a low flame temperature and low pollutant emissions. However, this situation introduces combustion stabilities and efficiency issues. To overcome these difficulties, a promising technology is to stabilize the flame by Nanosecond Repetitively Pulsed (NRP) discharges. The objective of this project is to elaborate and validate against experimental data a modeling route suitable to perform simulations of realistic turbulent combustion systems accounting for plasma-flame interactions. Experiments of plasma-assisted combustion will be conducted on two configurations: a bluff body flame and a swirled combustor representative of aeronautical combustion chambers. Large Eddy Simulations of plasma-assisted turbulent combustion will be performed and compared against experimental database. LES of a Turbomeca combustor stabilized by NRP discharges is the applicative challenge of the project.
