| 摘 要： | 研究了粘弹性Maxwell流体在具有周期运动边界的空间中的运动规律,结果表明流体的粘弹性对扰动具有较强的阻尼作用。用激光多普勒测速仪(LDA)测定了水及聚丙烯酰胺水溶液的瞬时速度分布,结果表明流体的粘弹性对紊流脉动有抑制作用。实验结果和理论分析是一致的。

| Abstract: | Influence of viscoelasticity on fluid abnormal motion Li Zhaomin, the University of Petroleum, East China, Dongying, Shandong Province. The characteristic of abnormal motion of Maxwell viscoelastic fluid is analyzed, with a equation under abnormal motion given. Tests indicate that fluid viscoelasticity has great damping action on disturbance. The determinations of instantaneous velocity of water and polyarylamide solution determined by Laser-Doppler anemometer (LDA) indicate that fluid viscoelasticity inhibit turbulent fluctuation. |
