A closer look at lightning reveals needle-like structures
Structural features have been identified on positively charged lightning channels that are not present on negatively charged ones. The discovery could explain why these two types of channel have
Stochastic equations generating continuous multiplicative cascades
Abstract:Discrete multiplicative turbulent cascades are described using a formalism involving infinitely divisible random measures. This permits to consider the continuous limit of a cascade
Electric arcs in open air
A summary of the phenomena associated with unconstricted arcs burning in open air in the current range 0.1 A to 20 kA is presented. Detailed current-voltage characteristics are given for electrode
Static and dynamic properties of arcs near plane surfaces
The static properties of an arc near a plane surface have been analyzed by extending Maecker's method to bi-cylindrical coordinates. A direct numerical solution was also carried out. The general
Generation and loss of nitrogen metastables formed by an electric arc at one atmosphere
Nitrogen at one atmosphere is activated by passing the fast flowing gas along the column of an electric are stabilized by rotating the flow by means of helically-wound grooves in the wall of its
Characteristics of diffuse electrical discharges stabilized in flowing air, argon and nitrogen
In studying electrically augmented flames it has been found that the fuel flow to a burner can be reduced to zero, leaving an electrical discharge stabilized in axially flowing air at atmospheric
A stable electrical discharge in air
An electric discharge has been stabilized by an axially flowing stream of air under conditions where it would normally be extremely unstable in quiescent air. Usually long arcs are stabilized by
Elektronen- und Gastemperatur in der positiven Säule der stromstarken Glimmentladung bei Atmosphärendruck
Measurements of the electron and gas temperatures and of the gradients and current densities in the positive column of a direct current glow discharge in the current range from 50 to 400 ma were
Elektronentemperatur und Elektronenrauschen in der hochfrequenten Fackelentladung
The noise temperature of the electron torch was determined at 14,000 deg K in air and nitrogen at atmospheric pressure at a measuring wave length of lambda = 20 cm. The power and resistivity for the
