Abstract
Influence of TiO2 nanoparticle lubricant additive on the load carrying capacity of a journal bearing is studied. Increase in lubricant viscosity due to presence of TiO2 nanoparticles is modelled using a modified Krieger-Dougherty viscosity model. Validity of modified Krieger-Dougherty model in simulating the viscosities of TiO2 nanoparticle dispersions in engine oil is experimentally verified. The pressure distribution and load carrying capacity are theoretically evaluated using a modified Reynolds equation for various TiO2 nanoparticle concentrations and aggregate sizes. Results reveal an increase in load carrying capacity of journal bearing using TiO2 nanoparticle lubricant additive as compared to plain oils without nanoparticle additive
