Abstract: Influence of Copper Oxide (CuO) and Boron Nitrate (BN) nanoparticle lubricant additive on the load carrying capacity of a journal bearing is studied in this paper. The load carrying capacity of a hydrodynamic journal bearing depends upon the viscosity of the lubricant being used. The dynamic analysis of hydrodynamic solid journal bearing operating with nanoparticle influenced commercial lubricants will be presented in this paper The inclusion of nanoparticles in the lubricant may affect the viscosity of the lubricant which leads to changes in the performance and characteristics of the lubricant. The proposed work is about to obtain pressure distribution in the clearance space of the solid journal bearing. Pressure generation and distribution measurements will be carried out using a Sommerfeld curve. Readings will be taken at a same interval. Pressure measurements will be carried out at a various loads. Same testing procedure will be carried out for conventional bearing.
