The influence of the spark discharge characteristic of the minimum ignition energy of a stoichiometric mixture of methane-air was studied theoretically. The investigation has been performed by solving numerically a set of the relevant differential equations. The spark discharge was simulated by a cylindrical pocket of combustible mixture having initially ambient conditions and a constant volumetric heat source. The methane and oxygen were assumed to react by a single reaction step. Predictions show that the minimum ignition energy is strongly dependent on the spark dimensions and its duration. Based on the present theoretical analysis an algebraic correlation between the minimum ignition energy of a stoichiometric mixture of methane-air and the spark dimensions and its duration has been proposed.
