Theoretical Prediction of Physical Properties (Viscosity) on 2D-based Nanofluids

Abstract

Nanofluids have been recently studied for efficient and high impact dielectric and tribological fluids, which possess superb thermal transport properties, compared to conventional fluids or lubricants. The present research theoretically analyzes, through Molecular Dynamic (MD) simulations, the physical performance of hexagonal boron nitride (h-BN) nanosheets reinforced mineral oil (MO). This analysis leads to the prediction of nanofluids performance, utilizing the Lennard-Jones potential. The computational results of viscosity performance are benchmarked at various temperature levels and nanofiller concentrations. The theoretical results indicate that the simulations presented can predict the behavior of nanoreinforced fluids.Keywords: molecular dynamics, nanofluids, hexagonal boron nitride, viscosity.

Carbon Nanotori Structures for Thermal Transport Applications on Lubricants

“…Nevertheless, even though nanofluids and nanolubricants are promising for many practical applications, care must be taken to maintain the integrity of the systems and eliminate undesirable properties. Potential drawbacks of adding nanoreinforcements to conventional materials pertain to viscosity, nanostructures’ agglomeration, and sedimentation, among others [ 15 , 16 , 17 ].…”
