Atmospheric pressure air plasmas are often thought to be in local thermodynamic
equilibrium owing to fast interspecies collisional exchange at high pressure. This …

This paper reviews optical diagnostic methods and approaches applied to study the
fundamentals of streamer discharges, considering the peculiarities of streamers developing …

A detailed experimental investigation of the mechanism of ultrafast heating and oxygen
dissociation produced by nanosecond repetitively pulsed discharges in atmospheric …

This work is a contribution to the understanding of the mechanisms controlling the transition
from a Townsend to a filamentary dielectric barrier discharge when the power increases …

The formation and decay of the thermal spark generated by a single nanosecond high-
voltage pulse between pin electrodes are characterized in this study. The influence of air …

RENEWED interest in lunar and Mars return has initiated studies of the aerothermal
environments produced around the vehicles used for such missions. This requires, among …

This paper presents an analysis of data previously reported from a test series in the Electric
Arc Shock Tube Facility for incident shocks composed of pure nitrogen. The present work …

Recent Fourier-transform spectrometry measurements of a wide array of rovibrational lines
of the first negative system of N2+ were used to develop a quantitative line-by-line radiation …

A spectroscopic database has been constructed for all the contributing electronic systems of
air diatomic molecules for elevated temperatures (up to 15,000 K). The electronic systems …

THE heat flux to a vehicle at lunar-return conditions consists of a component due to the
radiative flux from the high-temperature shock-layer gas [1]. The prediction of this radiative …
