Limiting Values

Minor fluctuations of velocity are frequently observed in gaseous mixtures whose compositions lie near to the limiting values of sustained propagation of detonation. Various possible origins of these fluctuations are discussed. In cylindrical tubes, they commonly take the form of a spinning detonation front. In order to study these effects in detail, previously described methods for making accurate observations near the limits have been extended in various ways. Use of multiple probes set radially in a standard detonation assembly permitted determination of the profiles of spinning ionization fronts to the detonation wave. In some cases, the existence of multiple spin heads detected by these means could be confirmed by soot-trace techniques. For any given mixture, fluctuations in the form of spinning ionization fronts are often remarkably reproducible in a particular tube.

At present, studying the parameters of shock waves at pressures up to 20 GPa entails a number of practical difficulties. In order to describe the propagation of shock waves, their initial parameters on the wall of the explosion cavity need to be known. With the determination of initial parameters, pressures in the near zone of the explosion can be calculated, and the choice of explosives can be substantiated. Therefore, developing a method for estimating shock wave parameters on an explosion cavity wall during the refraction of a detonation wave is an important problem in blast mining. This article proposes a method based on the theory of breakdown of an arbitrary discontinuity (the Riemann problem) to determine the shock wave parameters on the wall of the explosion cavity. Two possible variants of detonation wave refraction on the explosion cavity wall are described. This manuscript compares the parameters on the explosion cavity wall when using emulsion explosives with those obtained using cheap granular ANFO explosives. The detonative decomposition of emulsion explosives is also considered, and an equation of state for gaseous explosion products is proposed, which enables the estimation of detonation parameters while accounting for the incompressible volume of molecules (covolume) at the Chapman–Jouguet point.
