Abstract

Coupled with the coaxial counterflow nozzle, a novel dielectric barrier discharge apparatus has been designed to investigate the plasma assisted ignition of methane diffusion flame. Under the discharge condition, the ignition temperature decreases by around 100∼200 K. The simulation work based on OPPDIF code is promoted to decouple the thermal and chemical effects of plasma, which illustrates that the ignition temperature is more sensitive to the chemical effects. Through the chemical kinetics of methane oxidation at mild temperature, the CH₂ radicals generated by discharge play a significant role in the enhancement of ignition.
