摘要

本研究旨在开发一种基于液滴的微反应器，通过低频垂直振动实现主动混合，为通道微反应器的堵塞和复杂设计提供了一种替代方案。方法采用粒子图像测速（PIV）、脱色实验和基于运动粒子半隐式（MPS）方法的计算流体力学（CFD）研究振动参数对内部流动和混合性能的影响。在大多数情况下，实验观察到两种稳定的循环流动，而随机出现额外或不稳定的流动模式。在较大的振幅和较低的频率下，由于流动不稳定性的增强，混合效率提高。脱色实验显示出明显的内部和近表面流动行为。CFD结果表明，在x-y平面上有随机流动，在x-z平面上有稳定的循环，且涡度持续时间随着频率的增加而增加。这些发现证明了振动诱导的液滴混合在有机合成、生化反应和固液微过程中的应用潜力。

Flow and mixing characteristics in a droplet on a vibrating plate

Background

This study aims to develop a droplet-based microreactor that achieves active mixing through low-frequency vertical vibrations, offering an alternative to channel-based microreactors that suffer from clogging and complex design.

Method

The effects of vibration parameters on internal flow and mixing performance were investigated using particle image velocimetry (PIV), decolorization experiments, and computational fluid dynamics (CFD) based on the Moving Particle Semi-implicit (MPS) method.

Significant findings

Two stable circulating flows were observed in most cases of experiments, while additional or unstable flow patterns appeared stochastically. Mixing efficiency improved with larger amplitudes and lower frequencies due to enhanced flow instability. Decolorization experiments indicated distinct internal and near-surface flow behavior. CFD results showed random flow in the x–y plane and stable circulation in the x–z plane, with vorticity duration increasing at higher frequencies. These findings demonstrate the potential of vibration-induced droplet mixing for applications in organic synthesis, biochemical reactions, and solid–liquid microprocesses.
