组合状态方程在数值计算上的应用及分析

Application and analysis of a combinational equation of state for detonation products

摘要: 利用建立在爆轰产物实验等熵线数据上的组合状态方程以及常用的Jones-Wilkins-Lee (JWL)和Becker-Kistiakowsky-Wilson (BKW)爆轰产物状态方程进行了爆炸数值分析。状态方程数值计算的压力波形与实验波形的对比表明：组合状态方程和JWL状态方程计算的波形的到时、峰值、形状能够与实验吻合；BKW状态方程等熵式计算的数值波形峰值基本能够与实验吻合，但形状吻合不佳。

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.
