Numerical Simulation of Detonation in Fine Aluminum-Oxygen Mixtures with Hybrid Combustion Model

Abstract:

The detonation of fine aluminum-oxygen mixtures was numerical simulated using a hybrid combustion model. The emphasis was laid on the influence of the decomposition of Al₂O₃ on the detonation structure. Results showed that including the decomposition of Al₂O₃ will limit the gas temperature behind the detonation wave below a certain value. On the other hand, a double-wave structure will appear in the pressure profiles in cases with rich-dust condition if the decomposition of Al₂O₃ is not included.
