研究了微通道的柔性对T型连接微通道内两相流液滴生成过程的影响。微通道的一侧具有柔性的薄PDMS层，其在液滴产生时自然振动;变形频率与液滴形成的频率一致。此外，我们比较了与形成在一个传统的刚性微通道与一个软壁的微通道形成的油包水液滴的多分散性。我们发现，软壁的变形降低了液滴尺寸的多分散性。
We study the effect of softness of the microchannel on the process of droplet generation in two-phase flows in a T-junction microchannel. One side of the microchannel has a flexible thin PDMS layer, which vibrates naturally while droplets are generated; the deformation frequency coincides with the frequency of droplet formation. Furthermore, we compare the polydispersity of water-in-oil droplets formed with a microchannel with one soft wall with those formed in a conventional rigid microchannel. We show that deformation of the soft wall reduces the polydispersity in the droplet size.
