Thermo-hydraulic performance of a lubricant containing zinc oxide nano-particles: a two-phase oil
The first goal is to propose a two-variable equation for predicting the viscosity of zinc oxide-SAE50 nano-lubricant. In this way, the curve fitting was applied on laboratory data. Laboratory data have been reported in the temperatures ranging from 25 to 50°C of and the nanoparticles concentrations ranging from 0.125% to 1.5% previously. The presence of nano-particles leads to intensify the pressure descent and heat transfer, simultaneously. Therefore, the second goal was to evaluate the influence of nano-particles on the pressure descent and heat transfer.
