Effects of Non-Equilibrium Plasma on Counterflow Diffusion Flames

摘要

A new plasma assisted combustion system was developed by integrating a counterflow burner with nano-second pulsed non-equilibrium plasma. Xenon calibrated two-photon absorption laser-induced fluorescence was used to characterize the system by measuring the absolute atomic oxygen concentrations at the exit of the counterflow burner. The effects of plasma on the flames were examined by measuring the extinction strain rates of counterflow argon diluted methane/oxygen diffusion flames with and without plasma activation at low pressure (60 Torr). The experimental results were also compared with numerical simulations.
