The transport property of water inside Carbon Nanotubes
INTRODUCTION Water flow through carbon nanotubes (CNTs) has attracted great interests due to its potential practical applications in drug delivery and water desalination. For a fluid, the viscosity and the diffusion are two crucial transport properties reflecting the dynamic behavior of flow. They can be related by the Stokes-Einstein (SE) relation for a macroscopic fluid, but which may be breakdown for a nanofluid. To recognize the peculiar property of the nanofluid, numerous researches were devoted to it. By using the molecular dynamics (MD) simulations, the transport properties (viscosity and diffusion) of the water inside CNTs were extensively studied 1, 2. However, most of the previous works computed the transport property of the confined water with a specified density, which ignores the natural capability of the CNTs. Moreover, only the CNTs with the diameter varying from 10.8 to 21.7 A were focused on, and the smaller- or larger- diameter CNTs are seldom considered. Therefore, it is necessary to further study the transport properties of the fluid inside the nanochannel with a wider size and the applicability of the SE relation in this particular case.
