本文用电诊断法和高速摄影机研究了拉瓦尔喷管中滑动弧放电的动态特性。结果表明，当气体流量较小时，电压波形保持初始形状，而随着流量的增加，电压波形变得不稳定。在一个周期的前半段，电压上升，之后电压下降。在氮气和氧气中，电弧的击穿电压在3.3 - 5.5 kV之间，而在空气中在3.3-7.5 kV之间。电流I的波形基本保持稳定，对于氮气和氧气，电流I的最大值在0.28 ~ 0.46 A之间。随着流量的增加，在空气中的功耗先增加后减少;它保持在110-217 W的范围内，在氮气和氧气中逐渐增加。氧气中的功率消耗低于氮气中的功率消耗;对于所有三种气体，能量密度的输入随着流量的增加而减小。电弧的发展由高速摄像机跟踪和记录。对于高达1 m3 h−1的流量，循环稳定在10 ms。在较高的流速下，循环变得不稳定。
The dynamic behavior of gliding arc discharge generated in a Laval nozzle has been investigated by electrical diagnostics and a high-speed camera. The results show that the voltage waveform keeps the initial shape as the gas flow rate is small, while it becomes less stable with increasing flow rate. During the first half of a cycle, the voltage rises and after that it decreases. In nitrogen and oxygen, the break down voltage for the arc is between 3.3 and 5.5 kV, while it is between 3.3–7.5 kV in air. The waveform of current I remains almost stable; and for nitrogen and oxygen, the maximum value of current I is between 0.28 and 0.46 A. With increasing flow rate, the power consumption in air first increases and then decreases; it remains in the range of 110–217 W, and gradually increases in nitrogen and oxygen. The power consumption in oxygen is lower than that in nitrogen; the input of the energy density decreases with increasing flow rate for all the three gases. The development of the arc is tracked and recorded by a high-speed camera. The cycle is stable at 10 ms for flow rates up to 1 m3 h−1. At a higher flow rate, the cycle becomes unstable.
