In this work, influence of nanolubricants on the load carrying capacity of hydrodynamic journal bearing is studied. Increase in viscosity of lubricant oil with nanopartical as lubricant additives is modeled using different classical model and compared with Kriger-Doughetry viscosity model. This Kriger-Doughetry viscosity model for simulating viscosity of nanolubricant is validated by Experimental verification using reheometer. The pressure distribution and load carrying capacity are theoretically analyzed using Reynolds Equation for Reynolds boundary condition for different concentration of nanoparticles volume fraction. Result reveal increase in pressure and load carrying capacity of Journal bearing with nanolubricants in comparison to base oil.
