流增强的流介导传输
Streaming enhanced flow-mediated transport
摘要：
我们研究了主动体（主）纯粹通过非接触式流动介导机制操纵被动体（从）的能力，其动机是微流体设备和医学（药物输送目的）中的潜在应用。我们扩展以前的作品上的主的线性运动叠加周期性振荡的主动-被动缸对。在粘性流体中，这样的振荡产生附加的粘性流场，其用于增强从传输。我们看到，叠加振荡鲁棒地改善了在雷诺数范围内的传输。与无振荡结果的比较突出了工作中的流动机制，我们利用它来设计（主）增强运输的几何形状。这些原则被发现延伸到三维主动-被动形状以及。
英文摘要：
We investigate the capability of an active body (master) to manipulate a passive object (slave) purely via contactless flow-mediated mechanisms, motivated by potential applications in microfluidic devices and medicine (drug delivery purposes). We extend prior works on active-passive cylinder pairs by superimposing periodic oscillations to the master's linear motion. In a viscous fluid, such oscillations produce an additional viscous streaming field, which is leveraged for enhancing slave transport. We see that superimposing oscillations robustly improves transport across a range of Reynolds numbers. Comparison with results without oscillations highlights the flow mechanisms at work, which we capitalize on to design (master) geometries for augmented transport. These principles are found to extend to three-dimensional active-passive shapes as well.
