Abstract (english)
Emulsion explosives exhibit non-ideal detonation behaviour. The degree of their nonideality depends mostly on their composition and density (i.e., porosity), which in turn is a function of amount of glass-microspheres added. Variation in composition results in a significant difference in the detonation properties. This presents an additional difficulty for numerical modelling of detonation of emulsion explosives since the input parameters for the modeling (such are reaction rate, equation of state of unreacted explosive, etc.) differ for each composition and density. In this paper we present the results of calibration of the constants in pressure-dependent rate model incorporate in the Wood-Kirkwood detonation model. The constants are determined for several low-density emulsion explosives which contain up to 50% glass micro-balloons, in such a way that they reproduce the experimental detonation velocitiescharge diameters data. It was shown that pressure-dependent reaction rate model and the rate constants obtained in this study, can satisfactorily reproduce experimental detonation velocity-charge diameter for unconfined charges having densities in the range 0.5 to 1 g/cm3.
