本文从包含组分方程的完全ＮＳ方程出发，采用ＮＮＤ格式和Ｈ２／Ｏ２燃烧模型，通过求解ＮＳ方程，模拟了具有压缩拐角的二维管道和球头两类激波点火、燃烧流动。计算清楚地给出了流场中的激波、爆震波以及各种物理量的分布，并分析了激波、爆震波及其相互之间的耦合。在此基础上，讨论了稀释剂添加情况对流场的影响。计算中为了解决耦合方程组的刚性，提高计算的稳定时间步长，对化学生成源项，妥善地采用了隐式处理技术。
Starting from the complete NS equation containing component equations, two kinds of shock and combustion flows of two-dimensional pipeline and ball head with compression corner are simulated by solving the NS equation using NND format and H2 / O2 combustion model. The shock waves, detonation waves and the distribution of various physical quantities in the flow field are clearly given. The shock wave, detonation wave and the coupling between them are analyzed. On this basis, the influence of diluent addition on the flow field is discussed. In the calculation, in order to solve the rigidity of the coupled equations and improve the calculation of stable time steps, implicit processing techniques are properly adopted for the chemical generation source terms.
