摘要：
本文提出了一种利用受控涡环重连进行靶向颗粒输送的概念模型。被夹带的颗粒可在涡环核心内高效输运，而涡环通过自诱导推进。一对这种载有颗粒的涡环沿平行轨迹在流向方向运动时，会发生相互作用并导致涡环重连。重连使涡环发生拓扑变化，并伴随在垂直于运动方向的平面内产生快速排斥；这实际上将颗粒输送至侧壁上的预期输送位置。本工作阐释了该过程的物理机制以及靶向输送所需考虑的因素。
英文摘要：
A conceptual model for targeted particle delivery is proposed using controlled vortex ring reconnection. Entrained particles can be efficiently transported within the core of the vortex ring which is propelled via self-induction. A pair of these particle-transporting vortices travelling in the streamwise direction along parallel trajectories will mutually interact resulting in vortex reconnection. The reconnection causes a topological change to the vortex rings which is accompanied by a rapid repulsion in a perpendicular plane to the direction of travel; effectively, transporting the particles to the desired delivery site on the sidewalls. This work explains the physics of the process and the considerations for targeted delivery.
