平行刚性圆盘间有壁面滑移时宾汉流体的挤压流动

Squeeze flow of bingham fluid between two parallel disks with wall slip

两平行刚性圆盘间流体的挤压流动模型是一个基本的力学模型。流体与壁面存在滑移会对挤压黏性力产生影响。以Reynolds润滑理论为基础 ,研究了存在滑移时两刚性圆盘间宾汉流体的挤压流动。研究结果表明 ,随着滑移参数的增加 ,挤压黏性力减小 ,流体刚性层厚度增加 ;当滑移参数趋于无穷大时 ,所有流体都处于刚性运动状态 。

Squeeze flow between two disks is a classical mechanics model. Wall slip will affect the magnitude of squeeze viscous force. Based on the Reynolds' lubrication theory, squeeze flow between two parallel plates of a Bingham fluid with partial wall slip was considered. The results showed that the squeeze viscous force decreases with the slip parameter increases, the rigid region of the fluid increases with the slip parameter increases. When the slip parameter tends to infinit, the results of squeeze viscous force will be reduced to the case of the squeeze flow of rigid-plastic solid between two parallel disks.
