Performance Analysis of Couple Stress Fluid Operated Elastic Hydrodynamic Journal Bearing

Performance of bearings used in modern machinery is significantly affected by the elasticity of the bearing liner and viscosity of the lubricant. This paper considers couple stress fluid (CSF) model of the lubricant along with elasticity of bearing liner. The three dimensional (3-D) model of elastic...
