Abstract

In this work we present experimental investigations of methane-air mixtures ignition in a wide pressure range (3-450 atm) and experiments on ignition control by nanosecond gas discharge. This type of gas discharge as a source of active particles has a number of advantages: short time of discharge development, good reproducibility of the discharge parameters, spatial homogeneity over a large gas volume. Significant decrease of ignition threshold in a case of discharge action has been observed. Numerical modelling of active species production and chemical kinetics in the afterglow has been carried out for both high-pressure methaneair ignition without discharge and for discharge ignition. GRI-Mech3.0 mechanism was validated at high pressures.
