The recently developed Williamsburg equation of state (EOS) for detonation products is used in the one-dimensional ZND model for the reaction zone of a condensed explosive. This appears to be the first time a realistic EOS, capable of describing entropy and temperature changes accurately, has been incorporated into the ZND model. The unreacted explosive is described by a new Parsafar-Mason-Vinet EOS so that both phases receive the best thermodynamic treatment currently available. Results for the two extreme inter-phase assumptions regarding the thermal interaction of the reactant and product phases are presented and discussed.
