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.
