Abstract

The mechanism of igniting a combustible mixture of methane-air by means of an electrical spark is theoretically studied. The spark discharge was simulated by a cylindrical pocket of a combustible mixture having initially ambient conditions and a constant volumetric heat source. The oxidation of methane was assumed to proceed through an eighteen reaction step scheme. The analysis was performed by solving numerically the relevant conservation equations in the radial direction of a cylindrical coordinate system, and the evolution of the species concentrations, with time, as well as the temperature and burning velocity were predicted.
