“…Our previous work [7] showed that there is no temperature effect on the length of the secondary streamer over the range 293 K-1136 K, and this was explained in terms of the secondary streamer model developed by Sigmond [8]. A temperature effect on the length of the secondary streamer is also not observed in the present work over the range 292 K-1438 K, as shown in figure 10.…”

“…They concluded that the increased decomposition of O + 4 causes the largest increase in conductivity. In a previous work [7], we compared high-temperature ( 1136 K) and room-temperature pulsed positive streamer discharges at atmospheric pressure. To obtain the same values of E/n, the voltage V of the room-temperature discharge was increased so that the product VT (∝ E/n) was the same as that for the high-temperature discharge.…”

“…In this previous work [7], both n and T were changed between the high-temperature and room-temperature discharges. As a result, n and T both affected the streamer discharge, and the effects of temperature and density could not be separated.…”

The effect of temperature on pulsed positive streamer discharges in air is measured by comparing atmospheric-pressure, high-temperature discharges with low-pressure, roomtemperature discharges at the same air densities n and discharge voltages. Both discharges have the same reduced electric field E/n, so the differences between the two discharges only depend on the temperature, which is varied from 292 K to 1438 K. Temperature affects the discharge pulse energy most significantly; at 1438 K, the energy of an atmospheric-pressure discharge pulse is approximately 30 times larger than that of the corresponding 20.5 kPa, room-temperature discharge. Temperature also affects the shapes of the streamers when T 900 K, but no significant effect is observed for T 600 K. There is also no significant temperature effect on the spatially integrated intensity of N 2 (C-B) emission. However, temperature strongly affects the ratio of the integrated emission intensity to the discharge energy. No effect of the temperature is observed on the propagation velocity of the primary streamer or on the length of the secondary streamer.

“…This leads to an increase in the ionization events and discharge current at the same applied voltage. Furthermore, Ono et al [42] also noticed that the amount of charge transferred in a point-plate configuration increased due to the increase in the reduced electric field with increasing the temperature. This explains the increase in the current on increasing temperature at the same applied voltage.…”

This study thoroughly analyzed the gas-temperature dependence of nitrogen fixation in a dielectric barrier discharge powered by a nanosecond pulsed high voltage. The correlation between temperature (in the range of 300–600 K) and the humidity effects (H2O = 0.1% vol.–12.5% vol.) was systematically investigated at different oxygen contents (O2 = 5% vol.–40% vol.) in nitrogen. The nitrogen-content products were accurately evaluated by measuring them in the gas phase and that trapped in water, using Fourier transform infrared spectroscopy and ion chromatography, respectively. An examination of the current–voltage characteristics and optical emission spectroscopy indicated that temperature (within the tested range) had minor effects on the discharge characteristics, where the excitation processes slightly decreased while the dissociation and the ionization increased marginally. This eventually led to a constant amount of fixed nitrogen with temperature at a given gas mixture. However, a higher oxygen content promoted nitrogen fixation by increasing and accelerating the oxidation of fixed nitrogen to higher oxidation states. On the other hand, the temperature significantly affected the selectivity of the nitrogen-content products owing to its effect on the reaction rates of their formation and its significant influence on ozone decomposition. Operating the dielectric barrier discharge (DBD) at low temperatures favored the production of high-oxidation states of nitrogen that led to the formation of nitrate with free nitrite in water, which would be useful for agriculture. The results also indicated that operating the DBD at high temperatures is useful for obtaining high selectivity of NO, which can be useful for biological applications.

“…In recent years, three groups have investigated the effects of elevated gas temperature on streamer discharges in air [154,155,156,157]. Huiskamp et al [154] studied the effect of temperatures up to 773 K on positive streamers at constant gas density; they changed temperature and pressure simultaneously in order to keep the gas density fixed.…”

In this review we describe a transient type of gas discharge which is commonly called a streamer discharge, as well as a few related phenomena in pulsed discharges. Streamers are propagating ionization fronts with self-organized field enhancement at their tips that can appear in gases at (or close to) atmospheric pressure. They are the precursors of other discharges like sparks and lightning, but they also occur in for example corona reactors or plasma jets which are used for a variety of plasma chemical purposes. When enough space is available, streamers can also form at much lower pressures, like in the case of sprite discharges high up in the atmosphere.We explain the structure and basic underlying physics of streamer discharges, and how they scale with gas density. We discuss the chemistry and applications of streamers, and describe their two main stages in detail: inception and propagation. We also look at some other topics, like interaction with flow and heat, related pulsed discharges, and electron runaway and high energy radiation. Finally, we discuss streamer simulations and diagnostics in quite some detail.This review is written with two purposes in mind: First, we describe recent results on the physics of streamer discharges, with a focus on the work performed in our groups. We also describe recent developments in diagnostics and simulations of streamers. Second, we provide background information on the above-mentioned aspects of streamers. This review can therefore be used as a tutorial by researchers starting to work in the field of streamer physics.
