摘要

摘要: 为了研究二硝酰胺铵ADN(Ammonium DiNitramide)燃烧中的细节物理化学过程,建立了一个包含细节气相化学反应的ADN燃烧数学计算模型.该模型基于总连续方程,组元连续方程及能量守恒方程而建立,并运用了有限速率化学动力学原理,最后引入多组元系统状态方程以封闭方程组.此外,该燃烧模型还成功应用了包含34种组元和165个细节气相化学反应的化学动力学方案.使用该模型对0.3MPa下ADN燃烧气相组元摩尔分数与火焰温度分布进行预测,计算结果与试验数据相当吻合,说明该燃烧能够准确描述ADN气相燃烧波结构.

Abstract: A numerical calculation model with detailed gas phase reactions was developed to study the physical and chemical processes involved in ammonium dinitramide(ADN) combustion. The model was based on the conservation equations of mass, species concentration and energy, and takes into account finite-rate chemical kinetics. At last, the equation of state for a multicomponent system was employed to close the equations. A chemical kinetics scheme, containing totally 34 species and 165 reactions, was established and employed in the model. The model was applied to predict species mole fractions and temperature profiles in ADN gas phase flame at 0.3MPa. The agreements between calculation results and experimental data are very well. The results show that the model can predict ADN gas phase combustion wave accurately.
