Effects of natural convection on the characteristics of a long laminar argon plasma jet issuing horizontally into ambient air

Three-dimensional modeling results show that the appearance of the long laminar plasma jet is less influenced by natural convection even as it is issuing into ambient air horizontally. However, plasma parameter distributions may deviate from axi-symmetry in the jet downstream region, especially for the cases with lower jet flow rates, and affect the applicability of Abel inversion employed in plasma diagnostics.
