| Summary: | It is interesting to investigate fluid flow in nanochannel with a Janus interface (NCJI), especially when considering the asymmetric situations of wettability in the biology. The simulation results show that the temperature has a significant influence on the particle number near the hydrophilic surface because the desorption increases with the fluid temperature, while the external force has a little influence on the mass distribution. Because the viscosity of gas increases with temperature, the flow velocity of gas in NCJI decreases as the wall temperature increases. The flow in NCJI is neither Poiseuille-like nor plug-flow behaviors. This particular form of flow may be able to help us invent new nano-devices.
