Conditions of Initiation of Detonation in a Stoichiometric Hydrogen–Air Mixture by a Streamer Discharge

A numerical simulation of the conditions for the direct initiation of detonation in the region of a combustible mixture, in which its critical energy is minimum, has been performed using a streamer microwave discharge for the source of detonation initiation. The calculations were conducted on the ba...

Description
Summary:A numerical simulation of the conditions for the direct initiation of detonation in the region of a combustible mixture, in which its critical energy is minimum, has been performed using a streamer microwave discharge for the source of detonation initiation. The calculations were conducted on the basis of the model of the two-dimensional detonation in a combustible mixture, flowing in a cylindrical channel, with the use of the system of gas-dynamics and chemical-kinetics equations. The process of detonation initiation was considered as applied to a stoichiometric hydrogen–air mixture flowing in a cylindrical channel at different initial pressures. The requirements for the source of initiation of detonation in a combustible mixture were investigated with respect to the attainment of its critical parameters in practice.
