Influence of Various Parameters on Initiation and Stability of Detonations.
Abstract
The transition of flames to detonations has been investigated for various hydrogen-oxygen mixtures, for H2+N2O,CH4+2O2,C2H6+3.5O2,8C2H2+ 92 air and for C2H4+3O2. For the hydrogen oxygen mixtures the influence temperature (195 to 445 K) and of tube diameter (10 to 85 mm) on the initiation distance, initiation time and Oppenheim velocity of detonations has been measured. An attempt was made to correlate the Oppenheim velocity divided through the sound velocity of the unburned gas with such properties of the gas mixture as laminar flame speed, sound velocity, viscosity enthalpie of reaction a.o., which were put together so that they characterize an average velocity. In addition investigations of the velocity, stability and limits of methane chlorine detonations have been performed at various temperatures and pressures. (Author)
