Non-Equilibrium Kinetic Studies of Plasma-Assisted Combustion using Laser-Based Diagnostics

摘要

Experimental investigation of nanosecond- pulsed discharge in premixed Cftt/air mixtures at atmospheric pressure has been carried out using laser diagnostics. Electron temperature and number density are measured using laser Thomson scattering. Temperature of neutral molecules is measured by CARS. Finally, OH, CH and CH2O are probed using PLIF to identify their role in the reduction of ignition delay and in the improvement of lean burn capability relative to conventional spark ignition. Measurements are compared with numerical simulations performed using CHEMKIN-based code.
