Abstract
Static analysis of a misaligned externally adjustable fluid-film bearing is carried out thereby including turbulence and couple-stress effects in lubricants blended with polymer additives. A modified form of Reynolds equation, incorporated with the theory of micro-continuum and the concept of adjustability, is solved numerically, for various simulated operating conditions. The effects of turbulence and couple-stress on key performance parameters are presented. This study predicts that, an externally adjustable fluid-film journal bearing operating with negative adjustment configuration and lubricants with couple-stress, results in superior load carrying capacity with reduced friction and end leakage, as compared to a conventional partial arc bearing.
