在本文中，最近结束了广泛的准经典轨迹（QCT）研究[J。化学。物理。 104, 2825 (1996)] 用于模拟高超音速非平衡流中初级 NO 形成反应 N2+O→NO+N 的动力学。 QCT 数据用于获得该反应的热速率常数、反应物能量去除和产物能量处置速率的表达式。 QCT 结果与连续介质守恒流方程相结合，这些方程用于模拟高度在 75 至 87.5 km 之间的弓冲击紫外 2 (BSUV2) 流。发现使用 Macheret 和 Rich [Chem。物理。 174, 25 (1993)] 振动-解离耦合模型与 QCT 速率一起改进了 80 至 85 km 海拔高度的 NO 浓度预测。此外，根据 BSUV2 测量，发现 NO 的振动和旋转温度远高于气体中的 N2 和 O2。流中产生的 NO 量...
In this paper the extensive quasiclassical trajectory (QCT) study recently concluded [J. Chem. Phys. 104, 2825 (1996)] is used to model the kinetics of the primary NO formation reaction, N2+O→NO+N, in hypersonic nonequilibrium flows. The QCT data are used to obtain expressions for the thermal rate constant, reactant energy removal, and product energy disposal rates of this reaction. The QCT results are coupled with the continuum conservation flow equations, and these equations are used to simulate the Bow-Shock UltraViolet2 (BSUV2) flow at altitudes between 75 to 87.5 km. It is found that the use of the Macheret and Rich [Chem. Phys. 174, 25 (1993)] vibration–dissociation coupling model along with the QCT rates gives improvements in the NO concentration predictions at altitudes between 80 and 85 km. Also, it is found that the vibrational and rotational temperatures of NO are much higher than that of the N2 and O2 in the gas, in accordance with the BSUV2 measurements. The amount of NO produced in the flow ...
