通过数值模拟研究了超声速等离子体流动中物体后尾迹的形成。这些物体通过等离子体电流自我持续充电。在尾流与其他物体（如尘埃颗粒）相互作用的情况下，研究了不同系统条件下的尾流结构和马赫锥。附加的光电发射电流可以导致物体上的正电荷，并显著地改变尾迹。在二维和三维空间中采用颗粒在胞内的数值编码进行分析。
The wake formation behind objects in flowing plasmas is studied for supersonic flow velocities by numerical simulations. The objects are charged self-consistently by plasma currents. The wake structures and Mach cones are studied for various system conditions in the context of wake interactions with other objects, such as dust grains. Additional photoemission currents can lead to a positive charge on the object and significantly modify the wake. The analysis is carried out in two and three dimensions with particle-in-cell numerical codes.
