The effect of rotational nonequilibrium on the macroscopic parameters of the flow behind a normal shock wave in oxygen gas flow has been examined. The electron thermal equilibrium was taken into account where the electron temperature was equal to the vibrational temperature according to Park’s assumption. Therefore, only the effect of rotational nonequilibrium on the translational and vibrational temperature was analyzed. Rotational and vibrational relaxation time for the O₂-O₂ and O₂-O collisions proposed recently by Andrienko and Boyd are used. Also, the O₂ dissociation rates proposed by Kim and Park are used. The results obtained with the three-temperature model well reproduce the data obtained in shock tube for the shock velocity of 4.44 km/s.

已经研究了旋转不平衡对氧气流中正常冲击波后面的流的宏观参数的影响。根据Park的假设，考虑了电子热平衡，其中电子温度等于振动温度。因此，仅分析了旋转不平衡对平移和振动温度的影响。使用了Andrienko和Boyd最近提出的O ₂ -O ₂和O ₂ -O碰撞的旋转和振动弛豫时间。另外，O ₂使用Kim和Park提出的解离速率。用三温度模型获得的结果很好地再现了在冲击管中以4.44 km / s的冲击速度获得的数据。
