Abstract:
The investigations of the possibility of intensifying the processes of combustion in high-velocity flows of kerosene-air mixtures with the aid of electric discharges are used for studying the structure of flow and the distribution of products of plasma-chemical reactions behind a screen sloped toward the flow, with an auxiliary working medium in the droplet-gas and gas phases (kerosene, propane) being injected into the space under said screen. The experiments are performed at Mach number $M = 2$ and static pressure of $260$ torr. The distribution of static and total pressure in the region behind the screen and the field of Mach number are obtained in the absence of discharge, and the distribution of kerosene under the screen and in the wake behind the screen is visualized. A discharge with a current of $1$ A at a voltage of about $2$ kV is initiated above and behind the screen. The experimental conditions and geometry are found, at which the discharge behind the screen is spatially distributed. For these conditions, the distribution of the products of plasmachemical reactions in the case of injection of kerosene and propane is studied.
