Abstract
The Gliding Arc Discharge Plasma (GADP) IS umque non-thermal plasma that has relatively high plasma density, power and operating pressure in comparison with other non-equilibrium discharges. GAD is a new technology of non-thermal plasma. In recent years, a number of
researchers interested in this new technology for environmental
protection and for several of useful applications for human life. GADP
device has been constructed that can be operated at atmospheric pressure
consists of two identical diverging electrodes with length (44 mm), width
(26 mm), and thickness (15 mm) connected to the high voltage power
supply (6.6 kV) AC, 50Hz. A Rogowiski coil is used for measurement of
plasma current and for measurement of voltage, a resistive voltage
divider is used.
A device capable of generating GAD plasma which has been designed
fabricated and operated with Nitrogen or Argon gas as carrier gas with
different flow rates from 5 to 40 SCFH (Standard cubic Foot per Hour).
This design achieves the goals of producing GAD plasma under
atmospheric pressure.
The electrical parameters such as discharge voltage usmg a potential
divider with a ratio of 1000: 1 and discharge current using the voltage
across a 100 kQ resistor and using Rogowiski coil and Clamp meter were
measured and analyzed. The results of these electrical parameters showed
that the maximum values of 3.3 kV and 80 A for N2 gas of flow rate
equals 40 SCFH and their maximum values equal 2.7 kV and 50 A for
Argon at the same discharge conditions.
