Abstract The kinetic parameters of condensed phase global reaction are required to calculate temporal and energetic characteristics of the ignition and combustion of energetic materials (EMs). The heating rate of EM in these processes exceeds 1000 K/s and therefore the kinetic data obtained via using classical thermal analysis methods with heating rate of 1–50 K/min may not provide the processes adequate description. A solution to the problem was suggested more than 50 years ago by Merzhanov who noticed a possibility to determine required kinetic parameters from the EM experimental ignition delays. However, mathematical background and justification for this approach has not been performed. It is commonly assumed that the approach yields the true kinetics at high heating rates of EMs. The present work aims to verify the validity of Merzhanov's approach. Numerical calculations were performed using transient mathematical models of the EM ignition and the results of virtual ignition experiments were processed using Merzhanov's ignition criterion. The deliverables were the values of kinetic parameters that substantially differ from those used as input data in numerical calculations. The paper concludes about necessity of elaborating mathematically substantiated techniques for determining kinetic parameters of global exothermic condensed-phase reaction via using the EM ignition delays.

使用含能材料点火延迟数据确定放热凝聚相反应的动力学参数

摘要 凝聚相全局反应的动力学参数需要计算含能材料（EMs）点火和燃烧的时间和能量特性。在这些过程中 EM 的加热速率超过 1000 K/s，因此通过使用加热速率为 1-50 K/min 的经典热分析方法获得的动力学数据可能无法提供足够的描述。50 多年前，Merzhanov 提出了解决该问题的方法，他注意到有可能通过 EM 实验点火延迟来确定所需的动力学参数。但是，尚未执行此方法的数学背景和理由。通常假设该方法在 EM 的高加热速率下产生真实的动力学。目前的工作旨在验证 Merzhanov' 的方法。使用 EM 点火的瞬态数学模型进行数值计算，并使用 Merzhanov 的点火标准处理虚拟点火实验的结果。可交付物是动力学参数的值，这些值与数值计算中用作输入数据的那些值​​大不相同。本文总结了通过使用 EM 点火延迟来确定全局放热凝聚相反应动力学参数的必要性。可交付物是动力学参数的值，这些值与数值计算中用作输入数据的那些值​​大不相同。本文总结了通过使用 EM 点火延迟来确定全局放热凝聚相反应动力学参数的必要性。可交付物是动力学参数的值，这些值与数值计算中用作输入数据的那些值​​大不相同。本文总结了通过使用 EM 点火延迟来确定全局放热凝聚相反应动力学参数的必要性。
