Quasi-One-Dimensional Nonequilibrium Flow of Partially Ionized Argon with Different Species Temperatures
Abstract
Three-fluid nonequilibrium equations governing the flows of a partially ionized argon plasma are formulated. The equations are applied to the ionization-recombination nonequilibrium flow behind a strong normal shock wave, and to that in a convergent-divergent nozzle. The main consideration is made on the equipartition of the atom and ion thermal energies. For the flow behind a shock wave Ta{=}Ti is confirmed for a wide range of the upstream pressure. For the flow in a nozzle, Ta{=}Ti is usually confirmed. However, an example is shown in which Ti is in slight excess of Ta in the far downstream region from the throat.
