Burning of the Supersonic Propane-Air Mixture in the Aerodynamic Channel With the Stagnant Zone
Abstract
In the report the pulsed-periodical discharges created on an external surface of a flat plate being flown around of supersonic airflow and under condition of a stagnant zone located on a wide wall of the aerodynamic channel of rectangular section were investigated. It was show that the surface pulsed-periodical discharge results to ignition beforehand mixed supersonic propane-air fuel in the aerodynamic channel. In experimental conditions the combustion front speed reaches value of v(sub c)=40-45 m/s that well coordinates to the data which was got at investigation of burning into the fire-resistant channel. The kinetical model is working out for finding-out of influence of different channels on ignition of combustible mixtures in supersonic flow. The preliminary calculations demonstrate that at low initial gas temperature the induction time of H2-O2 mixture decreases on some orders of magnitude at taking into account of dissociation active radicals and charged particles.
