Analysis of couple stress fluid lubricated journal bearing with partial slip surface

摘要

The present study examines the effects of partial slip bearing configuration on improvement in load capacity and reduction in friction coefficient for journal bearing lubricated with couple stress fluids. The couple stresses effects are analyzed based on Stokes micro-continuum theory and partial slip configuration is analyzed using Navier slip boundary conditions. The nondimensional pressure and shear stress expressions are derived based on one-dimensional analysis using modified Reynolds equation. Partial slip of bearing surfaces has a potential to improve load carrying capacity for couple stress fluid lubricated concentric journal bearing.
