| 摘要: |
| 采用摩擦边界条件,引进合理的速度场,分析壁面滑移对两平行刚性圆盘间幂律流体挤压流动的影响.研究结果表明,滑移导致挤压黏性力减小,且存在壁面滑移时的挤压黏性力可以分解为无滑移时的解与滑移修正参数之积.结合相对滑移边界条件及与本构关系相联系的滑移边界条件进行对比分析,得到了不同滑移参数间的解析关系式. |

|
| Abstract: |
| Based on frictional boundary condition and a reasonable velocity field,the influence of wall slipping on the squeeze flow of power-law fluid between two parallel disks was analyzed.The results show that the squeeze viscous force is reduced because of slipping,and the squeeze viscous force can be expressed by the product of the solution without slipping and the modified slipping parameter.Comparing with the results of the relative slipping boundary condition and the boundary condition related to constitutive... |
| Key words: squeeze flow slip power-law fluid boundary condition viscous force |
