论文摘要
在二进制复合物血浆中研究了超音速粒子在界面上的渗透。受到国际空间站在PK-3加上实验室进行的实验的启发，进行了Langevin Dynamics模拟。观察到马赫锥体在界面上的演变，其中在界面上观察到侧向尾锋的扭结。通过比较轴向和径向速度的演变，我们表明界面孤立波是非线性的。背景粒子动力学在界面附近对穿透方向的依赖性表明，迁移率的差异可能是各种界面效应的原因。
The penetration of a supersonic particle at the interface was studied in a binary complex plasma. Inspired by the experiments performed in the PK-3 Plus Laboratory on board the International Space Station, Langevin dynamics simulations were carried out. The evolution of Mach cone at the interface was observed, where a kink of the lateral wake front was observed at the interface. By comparing the evolution of axial and radial velocity, we show that the interface solitary wave is non-linear. The dependence of the background particle dynamics in the vicinity of the interface on the penetration direction reveals that the disparity of the mobility may be the cause of various interface effects.
