The article deals with measurement of velocities of detonation in special charges constructed with an inner channel. The detonation course of these charges was investigated by measuring the velocities of detonation. The abnormalities found in the detonation course were interpreted as a consequence of the channel effect. For better understanding of the problem, the operation of channel effect was also investigated by means of a numerical simulation using the method of finite elements in the system ANSYS/LS DYNA3D.
