NUMERICAL SIMULATION OF THE IGNITION OF A FUEL MIXTURE BY A DISTRIBUTED SUBCRITICAL STREAMER DISCHARGE AND ITS BURNING IN A CHANNEL

A numerical simulation of the ignition of a fuel (propane–air) mixture in a combustion chamber by a subcritical streamer discharge, initiated at the wall of the working channel of this chamber in the electric fi eld with a strength lower than the breakdown one, on the basis of the gas dynamics equation defi ning the propagation of the combustion products in such a channel, the equation for the chemical kinetics of burning of a gas mixture in it, and the relation defi ning the formation and development of a streamer discharge in this mixture has been performed for diff erent values of the initial pressure in the channel, the excess of the propane in the gas mixture, and the number of streamerdischarge initiators in the channel. The results of the numerical calculations were compared with the available results of the corresponding physical experiment and experiment on the ignition of an analogous gas mixture by a multipoint spark discharge.
