Basic Parameters of Detonation of Hydrogen Mixtures. Part II

A large pool of data on the detonation hazard of hydrogen in mixtures with oxygen and air additionally diluted by inert gases and in the presence of steam in the mixture are reported. The most important parameter is the critical energy of detonation initiation, which serves as a measure of the explosion hazard of combustible systems: the smaller the critical energy, the more hazardous the mixture. The number of correct measurements of the critical energy of detonation initiation in scientific publications is rather limited (which is even more true for waves with different symmetries).
