摘要
Oscillating combustion is one of classic phenomenon in SHS.But the cause of its formation in a set of complex processes is unclear yet.With a two-step chemical reaction assumption and effects of other thermal dynamic factors,an auto-oscillating combustion has been gained in a solid SHS process on the macro-homogenous and micro-heterogonous model.Numerical solution shows that the change of chemical reaction is the main cause of the oscillating combustion.
