Abstract
Purpose
This paper aims to investigate atoms type and channel roughness effects on fluid behavior in nanochannel.
Design/methodology/approach
The results of mechanical properties of these structures are reported in this work by using molecular dynamics method.
Findings
The results show that nanochannel roughness is a limiting factor in flowing fluid in nanochannel. Moreover, fluids with less atomic weight have more free movement in ideal and non-ideal nanochannels.
Originality/value
For the study of mechanical properties of fluid/nanochannel system, the authors calculated parameters such as potential energy, density, temperature and velocity profiles of simulated fluids.
