Реферат: The data bank of information about the critical energy (E∗) in the initiation of detonation and combustion regimes is very important not only from a scientific point of view, but also in relation to hazards problems and the practical applications of such regimes in the construction of perspective combustion chambers and devices. The chemical energy release (Q∗) is the problematic parameter in the experimental measurement of detonation and combustion waves. The value of Q∗ and the spatial-time history [Q(r, t)] are especially important in the supersonic flow of chemically active mixtures. Some of the experimental and calculated results obtained on the values of E(r, t) and Q(r, t) for detonation waves are presented in this paper. In this case, the strong explosion model was used to recalculate the experimental wave trajectory. The results on a stoichiometric acetylene–oxygen mixture demonstrate the noticeable deviations of the experimental profile of energy release in multifront detonation waves from the profiles of available concepts of idealized one-dimensional detonation models. Also, it was established that the instabilities introduced by the initiator play a certain role in the total kinetic–gasdynamic instability of the chemical active mixture (for example, the sausage electromagnetic instability of an electric conductor with a current, the Meshkov–Richtmeier instability at the expanding boundary of the liquid metal of an exploding wire, etc.).
