Submicrosecond atmospheric electric discharge from the non-uniform electrode (tip) towards the plane electrode

Compact Uniform Field Electrode Profiles

In order to obtain high output powers from transversely excited pulsed lasers it is important to have a very uniform energy loading of the active gas medium. That is why there is a need for specially contoured electrodes which produce a very uniform field strength over a certain amount o f surface. A number o f authors have given solutions to this problem. Up to now, Rogowski profiles [ 1] are ...

Study of the Cryogenically Cooled Electrode Shape in Electric Discharge Machining Process

Electrical discharge machining (EDM) is well established machining technique mainly used to machine complex geometries on difficult-to-machine materials and high strength temperature resistant alloys. In the present research, the objective is to study the shape of the electrode and establish the application of liquid nitrogen in reducing distortion of the electrode during electrical discharge m...

Electrode Coverage Optimization for Piezoelectric Energy Harvesting from Tip Excitation

Piezoelectric energy harvesting using cantilever-type structures has been extensively investigated due to its potential application in providing power supplies for wireless sensor networks, but the low output power has been a bottleneck for its further commercialization. To improve the power conversion capability, a piezoelectric beam with different electrode coverage ratios is studied theoreti...

Determination of Electric Field at Inception Based upon Current-Voltage Characteristics of AC Corona in Rod-Plane Gaps

This paper deals with the measurement of AC corona inception voltage, Vincp, at the tip of a rod electrode using a hemispherically-capped rod-plane electrode configuration for various rod radii with a short air gap. Effects of atmospheric pressure and temperature variation on Vincp are investigated experimentally. An empirical equation for the field form factors of the hemispherically cappe...
