本文利用ＥＮＮ格式，通过求解包含非平衡效应的完全Ｎ－Ｓ方程，数值模拟了超声速燃烧流动中很有兴趣的Ｈ２／Ａｉｒ斜爆轰波冲压加速器的绕流。计算结果表明，本文采用的三阶格式能较好地捕捉激波、膨胀波和爆轰波，对粘性分离区的计算也有较高的分辨能力。数值模拟结果还清楚地阐明了冲压爆轰加速的流动机理，并建立了求解冲压加速器流场的数值计算软件及相应的推力计算软件。
In this paper, the ENN scheme is used to simulate the flow around a very interesting H2 / Air oblique detonation accelerator in the supersonic combustion flow by solving the complete N-S equation with the non-equilibrium effect. The calculation results show that the third-order scheme adopted in this paper can capture the shock wave, the expansion wave and the detonation wave better, and also has a higher resolution for the calculation of the viscous separation zone. The numerical simulation results also clarify the flow mechanism of stamping and detonation acceleration, and establish the numerical calculation software and corresponding thrust calculation software to solve the flow field of stamping accelerator.
