Many uncommon gas flow phenomena in nanopores have been found by experiments. Besides that, another special characteristic of gas flow at nanopore is that gas’s number density shows uneven distribution. From the point of molecular motion, gas’s number density would affect its dynamic viscosity, so it’s very necessary to study whether the gas’s viscosity is uneven. Due to the gas density’s fluctuation usually takes place near the wall surface so the present paper focuses on the gas’s viscosity near the wall of nanopore. Our molecular dynamics simulation results indicate that the gas’s viscosity in the region near the wall surface isn’t a constant and fluctuates greatly. The profiles of gas’s viscosity and gas number density coincide very well.
