Detailed Nonequilibrium Calculation of H2-He Flowfield

摘要

Thermochemical nonequilibrium processes in the H2-He flow behind a one-dimensional shock wave are numerically simulated. Ro-vibrational energy excitations and dissociation process of molecular hydrogen are considered microscopically by using the state-to-state transitions and the state-specific dissociation rate coefficients. The calculated flowfield using the present approach is compared with the calculations using the macroscopic reaction rate coefficients.
