Description
Summary:Currently, the computer simulation of the behavior of products containing explosives at various stages of their life cycle has become of increasingly greater importance. Computational methods have been verified by studying the propagation of detonation wave in channels of model distributors using high-speed photography. This paper focuses on the motion of a detonation wave at the bends of the channel and the formation of dark areas. The results obtained using a NANOGATE 2000 optoelectronic system based on a NANOGATE 22 high-speed camera with a shooting frequency of up to 10 9 fps are presented. The position of the detonation front moving with rotation at an angle of 60, 90, and 120° was first visualized with an exposure time of 20 ns and an interframe interval of 80 ns.
