Abstract

Abstract: The flow behavior of polymer solutions with relatively high viscosity in a coaxial micro-channel device was investigated.In the experiment, two kinds of flow patterns, dripping and jetting, could be formed.The jetting regime occurred as flow rate and viscosity of the fluids increased.The influence of two-phase viscosities and flow rates on drop size was investigated.The results could be used to guide the preparation of polymer micro-sized spheres.Mathematic models for predicting drop size in two flow patterns were established separately, and the calculated values fitted experimental results well.

Key words: micro-channel, liquid-liquid micro-dispersion, dripping, jetting

摘要： 进行了同轴环管微流控设备内黏性聚合物溶液的流动行为研究。研究发现通过调节两相流体黏度与流量,可以得到滴流和射流两种稳定流型,并且可以进一步实现液滴尺寸的调控。同时,还分别针对不同流型建立了数学模型用于液滴尺寸预测。所得结果可以用做利用微流控技术制备聚合物微球的理论指导。
