【 摘 要 】

In this paper, the impact of non-equilibrium rates of Zeldovich reactions N2+O↔NO+N, O2+N↔NO+O on shock heated air flows parameters are studied on the basis of state-to-state approach. The comparison of computed macroscopic parameters using different state-specific rate coefficients models for exchange reactions is presented. The influence of NO molecules vibrational excitation on total relaxation process behind a shock wave is shown.
