Abstract
The state of the art in the field of initiation of combustible mixtures is overviewed. Recommendations on using various formulas for estimating the critical energy (of both ignition of the mixture and initiation of detonation) are given. The importance of the spatial and temporal components in the energy release law is noted, especially for initiation optimization. Unsolved and new problems of the theory of combustion and detonation are formulated.
