摘要

控制涡流的驻点是实现颗粒定量定向运动的关键技术。提出了一种基于射流速度的涡流驻点控制方法。通过建立微流体动力学模型,模拟分析了射流速度对涡流驻点的影响,建立了射流速度与驻点的定量映射关系。最后,通过仿真验证了所提方法的可行性。总之,该方法为主动控制涡流驻点提供了技术手段。

Controlling Stagnation Point of Swirl Based on Jet Velocity
Controlling the stagnation point of the swirl is the key technology to realize the quantitative and directional movement of particles. This paper proposes a swirl stagnation point control method based on jet velocity. By constructing a microfluidic dynamic model, the influence of jet velocity on the swirl stagnation point is simulated and analyzed, and the quantitative mapping relationship between jet velocity and the stagnation point is established. Eventually, the feasibility of the proposed method is verified by simulation. Collectively, this method provides a technical means for proactive control of the swirl stagnation point.
