火炸药燃烧与爆轰产物的非理想普适状态方程

本文研究火炸药燃烧与爆轰反应产物的非理想状态方程的建立和应用。通过对载短维里方程、Haar—Shenker方程和BKW状态方程的评估,用“多方程组合法”建立的普适方程适用于从理想气体到类固体气体宽广的密度范围。该方程用于燃烧转爆轰研究。与过去使用的方程比较表明,燃烧转爆轰理论预测的准确性得到了提高。文中提供了奥克托金炸药反应产物的大量数据和方程的参数值。

General Non-Ideal Equation of State for Combusting and Detonating Explosives

This paper deals with the formulation and application ofthe non-ideal equation of state for products developed when burning or detonatingenergetic solid propellants and/or solid explosives. Included is the review of non-ideal gas equations of state(EOS)based on the virial EOS; the Haar-ShenkerEOS; and the Backer- Kistiakowsky-Wilson EOS. A general non-ideal EOS witha non-constant covolume function has been obtained by utilizing a "multi-equation combination" procedure, which can be used for a wide region of productdensities from ideal gas to solid-like gases. Comparison of the sensitivity ofthe general non-ideal EOS with other forms was made by utilizing aDeflagration-to-Detonation Transition(DDT)analyzes. The results showthat the accuracy of predictions of the DDT modeling using this general EOShas been improved. New methodology is presented for evaluating the parametersin the BKW EOS for HMX.
