摘要
针对传统爆轰参数计算中因采用产物温度平衡假设而导致含铝炸药爆轰参数预测偏差较大的问题，开展非平衡态下含铝炸药爆轰参数计算方法研究。基于铝粉在爆轰反应区内未参与反应的假设，考虑其非温度平衡热力学状态，通过冲击雨贡纽关系及一维球对称热传导理论确定铝粉在爆轰反应区的温度，建立非温度平衡条件下含铝炸药的爆轰参数计算模型。应用该方法计算不同铝粉含量RDX基含铝炸药的爆轰参数及爆轰产物状态方程参数。与EXPLO5程序的计算结果相比，新方法所得数据与实验值更为接近，且未出现误差随铝粉含量增加而增大的趋势。研究结果表明，引入非温度平衡方法能够更合理地描述含铝炸药爆轰过程中各组分能量分布，有效提高含铝炸药爆轰参数预测精度。
Abstract
Theextensiveutilizationof the temperature equilibrium assumption for detonation products in traditional thermodynamic codeshas been identified as a significant factor contributing to substantial discrepanciesbetweenthepredicted and experimental detonation parametersofaluminized explosives. To address this issue
the proposednon-equilibriumtemperaturemethodispredicated ontheassumptionthat aluminum powder does not participate in the reaction during detonation.This method determines the temperature of aluminum powderindependentlyby characterizing its shock compression and heat conduction processes
establishing a modified framework for predicting detonation parameters.This code is applied to calculate the detonation parameters and equation of state parameters of detonation products for RDX-based aluminized explosives with varying aluminum content.A comparison of the calculated datawiththeresults from the conventional code EXPLO5 showabetter agreement with experimental values
without theobservedtrend of increasing deviation as aluminum content rises. Thefindingsindicate that the non-equilibriumtemperaturemethodfacilitatesa morerational depictionof the energy distribution among the components of detonation products and effectivelyenhancesthe prediction accuracy of detonation parameters for aluminized explosives.
