Performance of Nano Particle Added Lubricating Oil Hydrodynamic Journal Bearing

The aim of this project is experimental analysis of Hydrodynamic journal bearing with Nano particle added lubricating oil. The dynamic analysis of hydrodynamic solid journal bearing operating under nano lubricants will be presented in this paper. The load carrying capacity of solid journal bearing mainly depends upon the viscosity of the Lubricant being used. The addition of nano particles on commercial lubricants may enhance the viscosity of lubricant and in turn changes the performance characteristics. In the proposed work is about to obtain pressure distribution in the clearance space of the solid journal bearing. CuO + BN nanoparticles are used in this study, CuO + BN based nano lubricant at various volume fractions, was prepared. The prepared samples exhibit good dispersion stability. The nano lubricant samples with different CuO + BN volume fractions are then subjected to an experimental analysis to study the Pressure generation and distribution in lubricating film of hydrodynamic bearing with increasing CuO + BN nanoparticle concentrations and load acting on bearing. Pressure generation and distribution measurements will be carried out using a Bearing testing machine. 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 (non nanofluid added lubricant) bearing.
