On detonation behavior of mixed fuels

An experimental study of detonation was carried out for mixed fuels (, and ). The results obtained demonstrate that detonation velocities of mixed fuels agree very well with normal C-J velocity and that detonation limits were not extended by the addition of a small amount of . As for mixed fuel, detonation velocities and detonation limits as a function of the equivalence ratio of the whole mixture of mixed fuel coincided with those of single fuel. However, the detonation induction time of a mixture of with a lower sensitivity to detonation decreased considerably with the addition of a small amount of . In addition, the influence of mixed fuels on the quasi-detonation and the fast deflagration in the process of DDT was investigated, showing interesting and complicated features in mixed fuel.
