| 摘 要： | 实验研究了部分水解聚丙烯酰胺(HPAM)稀溶液(水溶液)在内径为10.1 ~325 \mu m石英微管中的高剪切速率(1 215 ~23 120 s ^{ -1} )流动. 结果表明, 聚合物溶液在管径小于100 \mu m微管中的流动具有明显的微尺度效应, 实测流速高于由同种溶液在常规管径圆管中的流动规律所预测的流速. 实测流速与预测流速之间的偏离程度与管径和剪切速率有关: 相同剪切速率下, 管径越小, 偏离越明显; 在小管径微管中, 偏离随剪切速率的增加而减小, 而当管径超过30.7 \mu m后, 偏离不再随剪切速率的变化而改变.

| Abstract: | The high shear rate flow (1215~23120\,s^{-1})
characteristics of the partically hydrolyzed polyacrylamide (HPAM) in
silica micro-tubes with diameters in the range of 10.1~325\mum
were investigated experimentally. It is shown that the effect of the
microtule is obvious in microtubes with diameters less than 100\mum.
The experimental average
velocity is higher than expected which is the flow of the same solution in
general-sized tubes. In addition, the discrepancy between the experimental
and the expected average velocities is influenced by the diameter and
the shear rate. Under the same shear rate the smaller the diameter of
the microtube is, the more obvious the discrepancy is. In microtubes the
discrepancy decreases as the shear rate, however, if the diameters
beyond 30.7\mum, the discrepancy hardly varies with the shear rate
any more. |
