High Speed Photographic Investigation Of The Information Of Detonation Waves In A Stoichiometric Hydrogen Oxygen Mixture

A photographic study was undertaken of the detonation wave produced in a hemispherical chamber filled with a H2-O2 mixture at high initial pressures (600 psi). The study was directed at the driving processes in the driver of the UTIAS Implosion-Driven Hypervelocity Launcher. The shape of the luminous front of hemispherical detonation waves were photographed for waves produced in stoichiometric hydrogen-oxygen mixture at initial pressure of between 7 and 27 atmospheres. It was found that the wave pictures were not reproducible when tests were performed under apparently identical conditions. Further, the wave front was not always smooth and often asymmetrical.
