Abstract

Static characteristics of a journal bearing operating on TiO₂ based nanolubricant is obtained by a variable viscosity approach. The predicted shear viscosities of TiO₂ based nanolubricant at different volume fractions and aggregate particle sizes are obtained using modified Krieger-Dougherty model and are found to be in good agreement with experimental shear viscosities. The modified Reynolds equation considers the Krieger-Dougherty viscosities and couple stress effects of TiO₂ nanoparticle additives at different volume fractions and particle sizes. Results reveal a significant improvement in load carrying capacity of journal bearing operating on TiO₂ based nanolubricant as compared to plain oil without TiO₂ nanoparticles.
