| Abstract: | An experimental method for the study of deflagration-to-detonation transition(DDT) of combustible gas is introduced in this paper, and the merits of the method are discussed. The two characters of the flame during the period of DDT are described based on experimental results, a theoretical model of DDT flame is developed, and the mechanisms of the acceleration of DDT flame and the onset of overdriven detonation are explained based on the model. |
