Conclusions

Damping of overcompressed planar and cylindrical waves excited by a strong source in an explosive gas mixture has been studied experimentally. The quantitative characteristics of the process have been determined for super- and near-critical regimes. The dependence of cell size in a diverging attenuating wave on wave velocity has been established.

It has been shown that the “energy approach” produces quite reliable analytical expressions for description of the damping process. Consideration of the energy “deficit” produced by shift in the chemical equilibrium of the detonation products toward dissociation both in the front itself and in the internal region behind the front is of great importance.

A method has been proposed for description of the attenuation of a detonation wave with consideration of heat-liberation delay behind the front, which reflects the nonmonotonic velocity dependence at low source energy.
