Streamer Discharge Characteristics With Suspended Metallic Particles Under Low-Temperature and Subatmospheric Pressure in Nonuniform Electric Fields

Influence of Electrode Geometry on Streamer Discharge Characteristics in Long Air Gaps under Positive Lightning Impulse Voltage

PARAMETERS OF THE POSITIVE CORONA DISCHARGE STRIMER IN AIR IN ELECTRODE SYSTEM: A NEEDLE AND METAL DISK – PLANE

The paper is devoted to the study of the streamer propagation in a specific electrode system with a needle, the length of which is limited by a metal disk. The aim of the work is to determine the influence of the length of thin cylindrical needle in the electrode system with a metal disk on the streamer parameters duri...

Comparison of Plasma Parameters of Plasma Diffuse Jets and Red Columnar Sprites

Negative discharge characteristics in a long air gap triggered by femtosecond laser filaments

Femtosecond laser filamentation is a promising approach for active lightning protection, laser-triggered switches, and high-voltage gas discharges. For negative-polarity lightning, which dominates natural cloud-to-ground lightning, the strong stochasticity of negative-discharge inception and propagation remains a maj...

Streamer-to-spark transition in interacting multi-channel pulsed discharges with gasdynamic effects

The development of a streamer-to-spark transition in atmospheric-pressure air driven by a capacitor discharge in a resistor–capacitor circuit is simulated. The radial gasdynamic expansion of interacting plasma channels, along with the current–voltage characteristics, translational temperatures, electron density, pressu...

Investigation of AC–DC coupled diffuse discharge based on stacked mesh electrodes

Non-thermal plasma shows great potential for air purification because of its low temperature, abundant reactive species, and moderate power density. However, in atmospheric-pressure air, the short electron mean free path readily promotes filamentary discharge, leading to the localized distribution of discharge energy a...
