T-型微通道中液滴形成机制的CFD模拟
CFD simulation of droplet formation in microfluidic T-junction
摘要
Abstract
Droplet formation in a narrow-type microfluidic T-junction was simulated using the CFD package, FLUENT. The results confirm that with an increase in the capillary number, the drop formation in the T-junction investigated experiences the "squeezing" and "dripping" regimes successively, and between them, a "transient" regime obviously exists. Under both the two regimes, the wettability of the channel wall has a significant influence on the droplet formation. Droplets can be formed only when the continuous phase fluid preferentially wets the channel wall, and on the contrast to the " dripping" regime, the wettability of the channel wall significantly affects the drop size in the " squeezing" regime.关键词
