| 摘 要： | 壁面滑移是复杂流体流动中的一种普遍现象.对壁面滑移现象及其机理进行了总结,并讨论了几种检测滑移的方法.壁面滑移产生的机理可分为壁面吸附失效与缠结破裂,其关系十分复杂,且与流体的性质密切相关,还需要深入的研究.检测滑移的方法有标记法、激光-多普勒法、赫磁-共振法等.还阐述了壁面滑移与临界应力、颗粒浓度的关系以及滑移速度的...

| Abstract: | Wall slip is a commonly recognized phenomenon in flows of complex fluids.This paper presents a review on the existing research of wall slip and methods for its measurement.The mechanism of wall slip is classified into two categories: bonding-debonding,entanglement-disentanglement,both of which depend on the nature of the die material and the polymer melt.As the relationship is very complex,it requires further studies.So methodologies for detection of wall slip are discussed,including straight line marker te... |
