Experimental Study on Suppression of Detonation Waves

Abstract

In this experiment, detonation waves propagating in a stoichiometric propane-oxygen mixture through a channel containing an obstruction were investigated in order to clarify the cellular structure of the waves and also to find some methods for suppressing the detonation. The results suggest that triple shocks are formed by isochoric combustion accompanying spontaneous ignition behind the shock waves at the detonation front and that the propagation velocity must be decelerated to suppress the detonation, to the extent of keeping the temperature or the mixture so low that no spontaneous ignition takes place.
