Plasma-assisted combustion with nanosecond discharges. Part I: Discharge effects characterization in the burnt gases of a lean flame

This database contains the data published in the associated article, notably the plasma temperature, the electron number density, the discharge voltage and current, the number density of electronically excited species. They can be re-employed to validate any model of plasma-assisted combustion. All results are obtained at atmospheric pressure in a lean methane-air flame (Φ= 0.8) under the following experimental conditions: Air flowrate: 16 m3·h−1 (5.75 g·s−1), CH4 flowrate: 1.34 m3·h−1 (0.27 g·s−1), Incident pulse duration: 15 ± 1ns, Voltage amplitude of the incident pulses: 3.5 kV, Discharge repetition rate: 20 kHz. The theoretical flame thermal power is 13.3 kW if methane is completely burnt.
