Geometrical and electromagnetic effects on arc propagation in a railplug ignitor

Journal of Physics D: Applied Physics, 2007
Three-dimensional simulation of arc motion is presented for conditions representative of those for a railplug ignitor. A railplug ignitor is a miniature rail-gun used to deliver an arc ignition source for internal combustion engine applications. Computations explored the influence of the railplug geometry, effects of an external magnetic field, and ...

Seismic wave propagation beneath the Molucca Sea arc-arc collision zone, Indonesia

Tectonophysics, 1983
Abstract Seismograms of earthquakes from the Molucca Sea arc-arc collision zone, recorded at local stations, show a wide variety of coda envelope shapes and frequency contents. Some shallow (depth less than 20 km) events display large amplitude codas (relative to primary body waves) and lower frequency (2–4 cps) than deeper events which contain ...

Steady detonation propagation in a circular arc: a Detonation Shock Dynamics model

Journal of Fluid Mechanics, 2016
We study the physics of steady detonation wave propagation in a two-dimensional circular arc via a Detonation Shock Dynamics (DSD) surface evolution model. The dependence of the surface angular speed and surface spatial structure on the inner arc radius ($R_{i}$), the arc thickness ($R_{e}-R_{i}$, where $R_{e}$ is the outer arc radius) and the degree ...

A Method Based on Interharmonics for Flicker Propagation Applied to Arc Furnaces

IEEE Transactions on Power Delivery, 2005
In this paper, propagation in the network of flicker produced by rapidly varying loads is analyzed by means of a new frequency domain method. By this method, the flicker level can be determined at any bus of the network when one or several loads operate simultaneously.

ARC propagation, emission and damage on spacecraft dielectrics: A review

Journal of Electrostatics, 1987
Abstract This paper is a review of the literature on the subject of arc discharges on spacecraft dielectric materials that have become charged by energetic electrons and ions. The results discussed will be mainly from laboratory measurements of the properties of these arc discharges.

Structure of propagating arc in a magneto-hydrodynamic rail plasma actuator

Journal of Physics D: Applied Physics, 2015
Abstract The spatio-temporal evolution of a magnetically driven arc in a rail plasma flow actuator has been characterized with high-speed imaging, electrical measurements, and spectroscopy. The arc draws a peak current of ~1 kA. High-speed framing cameras were used to observe the complex arc propagation phenomenon.

Recurrent Tailward-Propagating Auroral Arcs during northward IMF

Auroral arcs in the high latitude are frequently observed during periods of northward interplanetary magnetic field (IMF). However, their generation mechanisms are not yet fully understood, due to the limited availability of simultaneous in-situ and optical auroral observations.
