Evaluation of viscosity and rheological characteristics of corn oil combined with graphene nanoplatelets for machining lubrication
Abstract
This study aims to analyze the thermal conductivity, dynamic viscosity and rheology of corn oil (CO) with added graphene nanoplatelets (GNPs).The addition of GNPs to CO uses variations of Φ = 0.10 %, Φ = 0.15 %, Φ = 0.20 %, Φ = 0.25 %, and Φ = 0.30 %.The highest thermal conductivity results were produced at a GNP percentage of Φ = 0.30 % with a value of 0.1620 W • m -1 • K -1 .The viscosity results show that the highest dynamic viscosity value is produced at GNPs Φ = 0.20 % at all temperatures.The rheology results show that the stable percentage 0.10 % and 0.20 % approaches Newtonian properties.
