摘要

Abstract

In current research

MWCNT-SiO

/oil hybrid nano-lubricant viscosity is experimentally examined. By dispersing 0.05%

0.1%

0.2%

0.4%

0.8% and 1% volume of MWCNTs and SiO

nanoparticle into the engine oil SAE 20W50

the temperature and solid volume fraction consequences were studied. At 40 to 100℃ temperature

the viscosities were assessed. The results indicated Newtonian behavior for the hybrid nano-lubricant. Moreover

solid volume fraction augmentation and temperature enhanced the viscosity enhancement of hybrid nano-lubricant. At highest solid volume fraction and temperature

nano-lubricant viscosity was 171% greater compared to pure 20W50. Existed models lack the ability to predict the hybrid nano-lubricant viscosity. Thus

a new correlation regarding solid volume fraction and temperature was suggested with R-squared of 0.9943.
