Abstract

A modified Krieger-Dougherty viscosity model is used in conjunction with classical two dimensional Reynolds equation to obtain theoretical steady state performance characteristics of two-axial groove journal bearing operating on TiO2 nano-particle dispersed engine oil. The modified Reynolds equation is non-dimensionalised and solved numerically by finite difference method satisfying the Reynolds boundary condition. A computational code is developed using MATLAB to simulate the bearing characteristics at different eccentricity ratios and volume fractions of TiO2 nanoparticle additives. Results reveal a significant improvement in load carrying capacity, hydrodynamic pressure distribution, and oil side leakage for two-axial groove journal bearing operating on TiO2 based nano-oil as compared to plain oil.
