摘要：
The thermophysical properties of MWCNT (50%)-ZnO (50%)/5W30 oil hybrid nanofluid (NF) are investigated at different conditions. Shear rates (SRs) of 666.5 s- 1 to 13,330 s- 1 and solid volume fractions (SVFs) of 0.05% to 1% are considered. Research shows that the behavior of the NFs is non-Newtonian and pseudo-plastic. Also, increasing the temperature has a special effect on reducing the viscosity. As temperature increases, intermolecular forces decrease and result in a reduction in viscosity. To predict the viscosity of hybrid NF with 5 W30 base oil, an experimental correlation is proposed considering the effect of temperature, SVF and SR. The stepwise regression method is used to correlate this relation. The R2 of the equation is 0.9982 which is in good agreement with the experimental results.
