A model for the combustion of aluminum particles in a gas is presented. Induction zones for ignition of aluminium particles behind shock and detonation waves are considered. It is shown that shock and detonation waves can arise behind a planar leading self-maintaining detonation wave propagating in a gas in the adjacent decompression wave in accordance with the mixture composition and flow conditions, which move with the same speed. A theoretical analysis is discussed for the possible situations and various cases of symmetry involving the formation of secondary detonation waves and combustion.
