Construction and spectral characterization of the gliding arc reverse vortex flow plasma system at atmospheric pressure

Abstract

In this paper, a low-cost reverse-gliding arc three-dimensional reactor with local materials and a homemade voltage source was proposed. This system works by pumping out argon gas while mixing in atmospheric air. The spectral properties of the resulting arc were investigated, as well as the calculation of electron temperature and density. The process of mixing air with argon gas is a novel method for obtaining nitrogen gas at a low cost and with ease of access. Nitrogen gas has numerous applications, and the findings are promising for future applications.
