摘要

利用交流驱动的单针射流等离子体装置

在介质管内产生了可以沿着介质管任意弯曲的超长射流等离子体

且可以喷射到介质管外的空气当中。利用高速相机对介质管内等离子体的传播过程进行拍照

研究了这种超长等离子体在介质管内的传播机制。研究发现

该装置在大气压下产生的等离子体长度可以达到约85 cm。在外加电压的正、负半周期

介质管内的等离子体具有不同的形貌和传播机制。正半周等离子体是以"等离子子弹"的方式向前传播

而负半周是以连续模式向前传播。分析发现

放电形成的空间电荷与介质管壁上的壁电荷之间形成的电场

是影响介质管内等离子体传播的主要因素。

Abstract

Using an alternating-current driving single needle jet plasma device

we produce a super long plasma jet (SLPJ) in the dielectric tube. The super long plasma jet (SLPJ) can be arbitrarily curved along the tube and can be sprayed into the air outside the tube. Photographing the propagation process of the SLPJ in the tube helps in understanding the corresponding transmission mechanism. It is found that

under normal atmospheric pressure

the SLPJ can reach about 85 cm

and owns different morphologies and transmission mechanisms during the negative and the positive half cycles. During the positive half cycle

the SLPJ spreads forward through the way of "plasma bullet"

while through the continuous model in the negative half cycle. Analysis reveals that

the electric field

produced by the space charge due to discharge and wall charge on the dielectric tube wall

is the main reason that influences the transmission mechanism.
