要約

The results of studies of firing and combustion of hydrocarbon fuel in a supersonic flow that was realized with the help of a module in relation to nonequilibrium electrical discharge generation are presented. The aerofuel combustion zone was not attached to the flat duct walls of the aerophysics setup (APS) but was closed to the module (anode−cathode), which had small drag. The results of the numerical computation of the spatial structure of flow over the module installed in the flat duct are presented. The possibility of gas-dynamic stabilization of a longitudinal discharge near the axis of a flat duct with closely spaced metallic walls is shown.
