Argon plume transition from a hollow swell to a diffuse swell with increasing amplitude of a trapezoidal voltage
文献摘要：
Atmospheric pressure plasma jets can generate a remote plasma plume,which usually presents a conical or cylindrical morphology.Despite a few morphologies being observed,efforts should be made to obtain more plume structures because streamer dynamics may be revealed from them.For this purpose,an argon plasma plume excited by a trapezoidal voltage is investigated,which presents two kinds of swells(a hollow swell and a diffuse swell)with increasing voltage amplitude(Vp).The results indicate that there are two positive discharges(Dp1 and Dp2)and one negative discharge(Dn)per voltage cycle for both of the swells.With increasing Vp,the inception voltage and discharge intensity increase for every positive discharge,while they decrease for the negative discharge.Fast photography reveals that the positive streamer(Dp2)leaves different tracks in the two swells,which are curved in the hollow swell and randomly branched in the diffuse swell.The different tracks of Dp2 are explained with the consideration of applied field strength and residual positive ions of Dp1.The existence of residual positive ions is finally verified from optical emission spectra.
