Abstract

Abstract

Boundary slippage was used to generate the load-carrying capacity of the hydrodynamic contact between two parallel plane surfaces. In the fluid inlet zone the fluid-contact interfacial shear strength on the stationary surface is set as low to generate boundary slippage there, while in the fluid outlet zone the fluid-contact interfacial shear strength on the stationary surface is set as high enough to prevent the boundary slippage occurrence there. The fluid-contact interfacial shear strength on the whole moving surface is set as high enough to prevent boundary slippage on the moving surface. These hydrodynamic contact configurations are analyzed to generate the pronounced load-carrying capacity. The optimum ratio of the outlet zone width to the inlet zone width for the maximum loadcarrying capacity of the whole contact is analyzed to be 0.5.
