Non-ideal detonation in combustible gaseous mixtures with reactive solid particles

In hybrid mixtures made of a combustible gaseous mixture with reactive solid particles in suspension, different propagation regimes of non-ideal detonation may be met: Double Front Detonations (DFD) Single Front Detonations (SFD). Their occurrence is linked to the nonmonotonous process of heat release. The problem is studied in the case of Hydrogen Air mixtures containing a suspension of aluminium particles. The domains of existence of those propagation regimes are predicted as function of the mass concentration off aluminium particles.
