Abstract : A flame photographic study has been made of the detonation attenuation in liquid explosive mixtures of tetranitromethane and ethyl iodide which occurs on a sharp change in the direction of propagation of the detonation front. The charge was flat and of constant depth; only the channel width (unspecified) was varied. The tetranitromethane/ethyl iodide (oxidizer/fuel) volume ratio was varied from 27/73 to 30/70. Deviations from normal detonation development occurred only at component ratios below 30/70. The following experimental facts were observed: (1) detonation wave attenuation in the narrow channel prior to exit into the wide vessel (at component ratio 27/73); (2) detonation wave attenuation on exit from the narrow channel into the wide vessel (28/72); (3) detonation wave attenuation on exit from the narrow channel into the wide vessel, subsequent amplification and development of the detonation after reflection of the detonation wave from the upper edge of the vessel (29/71); (4) slight attenuation of the detonation from the sides on exit into the wide vessel and subsequent normal development of the detonation (30/70).
