使用纹影摄影，从一个精细的毛细管为基础的微等离子体射流放电的氦气外流配置已被捕获的自由流条件。从层流到湍流的过渡是清楚地确定与等离子体的操作和不操作。在2.3 L的流速下。min（-1）时，该转变发生在距喷嘴54 mm处;然而，随着等离子体撞击（峰值电压为8 kV（p-p）），该转变减小到40 mm。
Using Schlieren photography, the helium outflow configuration from a fine capillary-based microplasma jet discharge has been captured for free-stream conditions. The transition from laminar to turbulent flow is clearly identified with and without operation of the plasma. At a flow rate of 2.3 L . min(-1) with no plasma operating, this transition occurs 54 mm from the nozzle; however, with plasma struck (peak voltages of 8 kV(p-p)), this reduces to 40 mm.
