Abstract

This paper presents the effect of CuO, TiO2 and Nano-Diamond nanoparticles additives in API-SF engine oil, on static characteristics of an externally adjustable fluid-film bearing. Modified form of Reynolds equation is solved numerically for various simulated operating conditions. Static characteristics evaluated are in terms of load carrying capacity, end leakage and friction. This study predicts that, a bearing having negative radial and negative tilt adjustments, and operating with API-SF engine oil blended particularly with TiO2 nanoparticles, results in better load capacity with reduced end leakage and increased friction, as compared to API-SF engine oil and Base oil without nanoparticle additives.
