Investigation of Transient Phenomena in Detonations

Abstract

Studies of three transient situations in gaseous detonations were made. The transient phenomena were obtained by propagating a detonation across a contact surface artificially introduced into the shock tube. Transverse wave trajectories were obtained by smoked foil technique as functions of the gas compositions on either side of the contact surface. The mechanism of disappearance of transverse waves was found to be the same in all cases. Theory and experiment showed that the strength of a transverse wave was independent of the degree of asymmetry of the intersection. The asymmetric intersection is not necessary to cause decay of the wave system.
