Abstract

Flow enhancement in nanotubes is of great potential to achieve ultra-fast fluidic transport. However the mechanism of such fast transport and its reduction as the tube enlarges to bulk scale is still unclear. In this work we establish a model to quantitatively correlate the flow enhancement and the fluid inhomogeneity to describe the enhanced transport and its evolution with the tube dimension. We found the fluid inhomogeneity at solid-liquid interface in nanotubes and its independence with tube size by dissipative particle dynamics (DPD) simulation. Based on that, we establish novel theoretical models for the penetration rate in nanotubes with parameters related to the fluid inhomogeneity for the first time, which can achieve quantitatively prediction for nanoflow enhancement and are valid through all scales.
