Finite-Element Simulation of Electrical Discharge Machining (EDM) Process


I. INTRODUCTION
Electric discharge machining (EDM), sometimes
colloquially also referred to as spark machining, spark
eroding, burning, die sinking or wire erosion, is a
manufacturing process whereby a desired shape is obtained
using electrical discharges (sparks). Material is removed
from the workpiece by a series of rapidly recurring current
discharges between two electrodes, se ....etc

ABSTRACT
High intensity discharge lamp (HID) presently used for urban street light are based on principle of gas discharge, thus the intensity is not controllable by any voltage reduction method as the discharge path is broken. White Light Emitting Diode (LED) based lamps are soon replacing the HID lamps in street light. Thus intensity control is now possible by pulse width modulation based on sensing the movement and density of vehicles. The pulse width becomes very narrow on sensing no movement of vehicles. As the ....etc

Ozone Generation From corona discharge

Abstract
The phenomenon of violet glow, hissing noise and the production of ozone
gas in the overhead transmission line known as corona is used in our project for the
production of ozone gas. The gas produce out of the device can be used for the
treatments of drinking water disinfections and air purification.
The device has a discharge tube in which high electric field is applied so
as to breakdown the ozone present in the air. This ph ....etc

ABSTRACT
Water is most abundant component on earth surface, constituting about 70% of the planet surface. Although some 70% of the Earth's surface is covered by water much of this is saline. However freshwater is available in almost all populated areas of the earth although it may be expensive to access the water and the supply may not always be sustainable. Only 4% of the available water is suitable for drinking purpose.
Throughout most of the world, the most common contamination ....etc
