Master Equation Analysis of Post Normal Shock Waves of Nitrogen

One-dimensional post normal shock flow calculations are carried out using state-of-the-art thermochemical nonequilibrium models. Two-temperature, four-temperature, and electronic master equation coupling models are adopted in the present work. In the four-temperature model, the rotational nonequilib...

Description
Summary:One-dimensional post normal shock flow calculations are carried out using state-of-the-art thermochemical nonequilibrium models. Two-temperature, four-temperature, and electronic master equation coupling models are adopted in the present work. In the four-temperature model, the rotational nonequilibrium is described by Parker and modified Park models. In the electronic master equation coupling model, recently evaluated electron and heavy-particle impacts and radiative transition cross-sections are employed in constructing the system of electronic master equations. In analyzing the shock-tube experiments, the results calculated by the state-of-the-art thermochemical nonequilibrium models are compared with existing shock-tube experimental data. The four-temperature and electronic master equation coupling models with rotational nonequilibrium described by the modified Park model approximately reproduce the measured rotational, vibrational, and electronic temperatures.
