Abstract
The detonation processes in chemically active bubble systems at high initial pressures are calculated numerically. The dependences
of detonation wave velocity at sub- and supersonic regimes of propagation on molar fraction of gas in the mixture and on initial
pressure have been calculated for the first time. The Chapman-Jouguet condition for supersonic bubble detonation wave is obtained.
The principal possibility for
a different detonation wave structure in the case of propagation in the mixture with high initial pressure and longitudinal
gradient of bubble volume fraction is predicted.
