Abstract

Abstract: The regular oblique reflection and Mach reflection of detonation waves in condensed explosive after their interaction are investigated using the three-wave theory and the Whitham's method on the basis of Jones-Wilkins-Lee (JWL) equation of state (EOS). The JWL EOS-based calculation model of regular oblique reflection, reflection pressure and Mach stem height is derived. A theoretical calculation method is proposed for the slowly changed function k(ξ) in the modified Whitham's method. The calculation model was verified with the experimental data of PBX 9501 and JH-2 explosives. The calculated results are in good agreement with the experimental results, which means that the calculation model based on JWL EOS can be used accurately to predict the detonation parameters distribution and propagation process of regular oblique reflection and Mach reflection.
