Emission and radiative cooling of xenon plasma behind a strong shock front

Generation of Surface-Treating Plasma by a Superadiabatic Compression Ballistic Plasmatron

“…-nondimensional area of the heat transfer; -nondimensional radiation power [12], [13], -Stefan-Boltzmann constant, -absorption coefficient of plasma [13], -reduced linear size, equaled and -radiation ability of plasma, reflecting the contribution of the different transitions, basically, free-connected ones [8], [10], -flow of gas mass through the orifice in the second piston -throttling function, and -the pressure behind and ahead second piston respectively. The working gas was Ar or Xe.…”

Heat-engineering units for the generation of dense high-temperature gas

“…In this case, one still has to clarify the possibilities of developing a medium with inverse population, methods of producing such medium, working pressures, and breakdown (ionization) techniques [79,123].…”

“…In shock tubes it is impossible to compress gas to densities that are much higher than the initial values; however, it is quite possible to accomplish the emergence of radiation in a shock wave [64,79]. Shock and impulse electric-discharge wind tunnels (the electricdischarge method of gas heating is realized in the latter [25,29,80], and the energy is supplied using a capacitor bank discharge) are extensively employed in laboratory investigations, as well as in experimental aerodynamics [29,81,82].…”
