Numerical study of atmospheric-pressure argon plasma jet propagating into ambient nitrogen
文献摘要：
A 2D axial symmetry fluid model is applied to study the features of an atmospheric-pressure argon(Ar)plasma jet propagating into ambient nitrogen(N2)driven by a pulsed voltage,emphasizing the influence of gas velocity on the dynamic characteristics of the jet.The results show that the Ar jet exhibits a cylindrical-shaped channel and the jet channel gradually shrinks with the increase in propagation length.The jet propagation velocity varies with time.Inside the dielectric tube,the plasma jet accelerates propagation and reaches its maximum value near the nozzle.Exiting the tube,its velocity quickly decreases and when approaching the metal plane,the decrease in jet velocity slows down.The increase in gas speed results in the variation of jet spatial distribution.The electron density presents a solid structure at lower gas flow speeds,whereas an annular structure can be observed under the higher gas flow velocity in the ionization head.The jet length increases with the flow velocity.However,when the flow velocity exceeds a critical value,the increase in the rate of the plasma jet length slows down.In addition,the gas velocity effect on the generation and transport of the reactive particles is also studied and discussed.
