Abstract : The processes that occur when a self-sustaining detonation propagates into a channel whose cross-section area is increasing have been observed experimentally. The detonation tube has a 3 x 1/4 inch cross-section and at the test section one of the narrow walls was opened at angles which ranged from 5 degrees to 45 degrees over a distance of 24 inches. The detonations were propagated at initial pressures of 75 to 300 torr in stoichiometric hydrogen-oxygen mixtures diluted with 20%, 50% and 70% argon. Smoked foil records were obtained to determine the effort of channel expansion on transverse structure. (Modified author abstract)
