Description
Summary:Measurements were made of pressures, wave and flame speeds in slightly confined and practically unconfined hydrogen air mixtures to study the mechanism of transition from deflagration to detonation to shed further light on this phenomenon transition studies were also made in very long tubes. According to the results of these studies it appears that hydrogen-air clouds may detonate when the volume is sufficiently large. A rigorous analytical study was made of the performance of supersonic ramjets. The results of these calculations show that efficient operation involves impractical pressures in the combustion chamber and very large diffuser inlet and nozzle exit areas. (Author)
