Abstract

Pulse dielectric barrier discharge jet is widely used in various fields. Pulse discharge can produce plasma with high chemical activity and uniformity. However, pulse discharge's instantaneous high power and energy deposition can also cause changes in the flow field, so further research is needed. This paper studied the characteristics of the flow field of pulse needlering dielectric barrier discharge jet. The schlieren imaging technology was combined with a high-speed camera to record the spatial-temporal resolution images of the flow field under different electrical parameters. It was found that with the increase of voltage amplitude, the emergence time of downstream turbulent vortices was advanced. The turbulent vortex average propagation speed (-3 m/s) was much lower than that of the jet (104m/s) but close to the gas velocity (2.97 m/s). However, the pulse width and repetition frequency had little effect on the flow field. It was also considered that the formation of turbulent vortices was related to the forward momentum of gas molecules.
