INVESTIGATION OF THE MECHANISMS OF DECOMPOSITION, COMBUSTION, AND DETONATION OF SOLIDS

Abstract

THE FLAME REACTION B TWE N PROPANE AND AIR HAS BEEN STUDIED AT 1 ATMOSPHERE IN A SYSTEM WHICH PERMITTED EXAMINATION BY Schlieren optics of the jet streams and the reaction zone. With 4.6 mm jets at a separation of 3.5 cm, initial studies yielded a value of 0.11 g per sq cm per second for the apparent flame strength. A 'dump' system was used to examine the reaction between gaseous HClO4 and approximately 10 mole% of NH3 at 230 C. Without complete gas analysis data, it appears that the N 3 initiated a very rapid decomposition of HClO4. An exothermic reaction which was too rapid to measure by st ndard sickle-gage techniques occurred at the time of mixing. The flow reaction between HClO4 and NH3 was carried out with the gas streams at approximately 180 C and a reaction pressure of 60 mm. The instantaneous reaction resulted in formation of NH4Cl at the oxidizer jet nozzle. (Author)
