Description
Summary:Of interest in this study was the collision of a flame with a shock wave emitted from the flame itself and propagated in the opposite direction to the flame after reflection at the end of a combustion tube. The transition to detonation occureed at a critical initial pressure for various tube lengths. It did not begin below a certain limit of the flame velocity at the collision point and it occurredd with no stimulus from the reflected shock wave beyond a critical flame velocity. Relations between the detonation induction distnce and the minimum flame velocity leading to the detonation and relations between the flame velocity at the collision point and the distance from the collision point and the detonation point are presented.
