This work reports average electron temperature ( T e) and electron density ( n e) of an atmospheric argon rotating gliding arc ( R G A), operated in glow-type mode, under transitional and turbulent flows. Both T e and n e were calculated near the shortest ( δ) and longest ( Δ) gap between the electrodes, by two different methods using two separate...

Successful application of plasma-activated water (PAW) as an alternate source of nitrogen for agricultural application requires low specific energy consumption. This work reports on a dielectric barrier discharge (DBD) plasma reactor for the generation of PAW having low specific energy (SE) consumption. The SE to produce N in PAW was 3.26 GJ/kg of...

This work investigates the reliability of the function called ‘regionprops’ which is used for measuring the 2D length of the plasma discharge. Work was conducted in a Rotating Gliding Arc ( RGA ) reactor, using air as plasma forming gas. Arc rotational images at three different gas flow rates i.e. 5, 25 and 50 litres per minute LPM were captured us...

This article investigates the effect of gas flow rate on arc discharge mode and plasma chemistry in a nonmagnetic rotating gliding arc reactor. This article is conducted using oxygen as a plasma forming gas under transient (5 LPM) , turbulent (25 LPM) , and highly turbulent (50 LPM) flow conditions. The voltageendash current ( V-I ) characteristics...
