Experimental study of the characteristics of supersonic expansion of plasma jets from an arc source
Abstract
Plasma probes and spectroscopy were used to investigate supersonic expansion of strongly underexpanded argon plasma jets from the arc source for a plasma stagnation temperature of 9,500-13,000 K and a stagnation pressure of 1000-8000 Pa. Electron density and temperature, plasma velocity, and the temperature of the heavy component were measured; and the disruption of ionization and thermal equilibrium in the flow field was examined.
