Experimental InYestlgatlon on effect of aluminium oxide nano-particles on hydraulic oil of HEMM lubricant

摘要

In this study, the effect of Al_2O_3 nano-particles on density and viscosity of hydraulic oil (Hydrex 100) used in heavy earth moving mining (HEMM) equipment is experimentally investigated. In base fluid (hydraulic oil) different volume fraction of Al_2O_3 (0.01%-l%) nano-particles are added. The present data show that with the increasing temperature the viscosity and density of base fluid and nano-fluid decreases, whereas it increases with increasing particle volume fraction. According to the experimental results of the viscosity, a new correlation for predicting the viscosity of nano-fluid with varying particle volume fraction has been presented.
