Effect of SWCNT volume fraction on the viscosity of water-based nanofluids.

Nanofluids have received a great deal of interest in recent years because of their various unique features. According to the findings, the addition of nanotubes to the base materials can drastically alter their properties. In the present work, the viscosity of a typical water-based nanofluid containing single-walled carbon nanotubes is estimated using the molecular dynamics simulation for different volume fractions ranging between 0.

Molecular dynamics study of nitrogen diffusion in nanocrystalline iron.

To obtain a deeper understanding of the production of advanced high-nitrogen steels, the diffusivity of nitrogen in bcc iron was investigated at the nanoscale by molecular dynamics (MD) simulation using the modified embedded-atom method (MEAM) interatomic potential. The diffusivity of nitrogen was calculated by mean square displacement (MSD) at different temperatures (773-1473 K) and nitrogen concentrations (0.23, 0.
