MINIMUM IGNITION ENERGY FOR THE NANOSECOND PULSED DISCHARGE IGNITION

A.A. Tropina

The model of mixture laminar combustion and the minimum ignition energy calculation for the case of nonequilibrium plasma ignition of the nanosecond pulsed discharge has been proposed. The model is based on the transport equations for the multicomponent reacting mixture combined with the equations for translational and vibrational temperatures. The data about the minimum ignition energy dependence on a pulse width and mixture composition were obtained. The evaluation of the input of the mixture vibrational excitation by a nanosecond impulse to minimum ignition energy was carried out.

Key words: repetitive nanosecond pulsed discharge, minimum ignition energy, nonequilibrium plasma, numerical modeling.
