Ignition, Combustion, Detonation, and Quenching of Reactive Mixtures.
Abstract
The detonation induction distances in hydrogen-air mixtures are greatly shortened when the initial temperature of the explosive gas mixture is reduced. A new technique has been developed to calculate the effect of mixing of different gas jets on the final properties of the gas mixture. Flame speed measurements in large, nearly unconfined hydrogen-air mixtures revealed that the flame accelerates and that the speed increases with increasing volume of the explosive mixture. A shock tube has been set up to study the effect of a flame arrestor on the strength of a normal shock wave. A rectangular combustion chamber with windows is used to investigate the mechanism of deflagration quenching with various sponge and grid type flame arrestors. Further calculations have been made to determine the performance of supersonic ramjets. (Author)
