PERFORMANCE ANALYSIS OF SURFACE TEXTURED HYDRODYNAMIC JOURNAL BEARING UNDER INFLUENCE OF NON-NEWTONIAN LUBRICANT

The operating and geometric parameters of textures affect the static, dynamic, and stability performance characteristics of a hydrodynamic journal-bearing system.The present work investigates the influence of spherical textures on the performance parameters of a hydrodynamic journal bearing system.The flow of a lubricant is assumed to be Non-Newtonian and Reynolds's equation governing the flow of a lubricant between the space in the bearing and the journal is solved by a finite-element method (FEM).The computed results indicate that the spherically textured two lobe hydrodynamic journal bearing provides better improvement in the performance parameters than two lobe hydrodynamic journal bearing with plain surface.
