Abstract

Abstract

A combinational equation of state based on the experimental isentropic data for detonation products was deduced. Different equations of state for detonation products were used to simulate numerically detonation behaviors of explosives. Comparison between the experimental and numerical results shows that the arrival times, pressure peaks and wave forms computed by the Jones-Wilkins-Lee (JWL) equation of state and the combinational equation of state are in better agreement with the experimental results than those computed by the Becker-Kistiakowsky-Wilson (BKW) isentropic equation of state.
