Abstract: | The detonation velocity deficit in bending flexible detonating fuses is studied, based on the detonation wave’s corner effects
and delay time phenomenon. A physical model and a theoretical mathematical equation of the detonation velocity deficit are
established by using the dimensional analysis. Based on experimental data, a semi-empirical formula of the detonation velocity
deficit for bending fuses in the same charge size is derived. It is shown that the detonation velocity deficit and the reciprocal
of the curvature radius are in an exponential relationship. |
