Journal ArticleDOI
Variation of axial temperature in thermal plasma jets
TL;DR: In this paper, the excitation temperature of a spray torch was determined using the atomic Boltzmann method and the spatially integrated intensities of emission lines resulting from Ar-I transitions in the wavelength region 400 - 451 nm have been measured.
Journal ArticleDOI
A comprehensive study of different gases in inductively coupled plasma torch operating at one atmosphere
TL;DR: In this article, a numerical simulation of ICP torch using argon, nitrogen, oxygen, and air as plasma gas has been investigated using computational fluid dynamic (CFD) software fluent©.
Journal ArticleDOI
Axial variation of electron number density in thermal plasma spray jets
TL;DR: In this paper, the electron number density has been measured in a plasma spray torch using Stark broadening of H 1 /β 2 and Ar-I (430 nm) line profile.
Journal ArticleDOI
