Abstract:
Results of experimental investigations of an expanding multifront detonation wave are presented. Two stages of spontaneous formation of new disturbances and transverse waves on the expanding detonation-wave front are observed. The main mechanisms of reinitiation of detonation waves are discussed. Two-dimensional numerical simulation of the dynamics of a multifront detonation wave in a linearly expanding channel is performed. The effect of spontaneous formation of new disturbances and new transverse waves is confirmed by computations, and the main mechanism of multiplication of transverse waves is the instability of detonation-wave-front elements at the stage they cease to be in the overdriven state and are attenuated during expansion.
Keywords:
