Overview

Molecular dynamics simulations reveal how confinement alters viscosity and enhances transport in carbon nanotubes compared to rectangular channels.

Key Points

  • Carbon nanotubes show significantly higher flow velocities and lower effective viscosities than rectangular channels due to unique interfacial interactions.
  • Molecular dynamics simulations demonstrate that confinement enhances directional transport efficiency and reduces activation barriers.
  • In contrast to carbon nanotubes, rectangular channels promote plug-like flow, indicating the critical impact of wall–fluid coupling on viscosity.
  • Findings highlight how confinement geometry materially influences transport at biologically relevant scales and suggest a framework for mesoscopic flow models.
