Effect of bounding wall vibrations on a flow of simple fluid passing through flat nano – channels

We present results of molecular dynamics simulations of a fluid flow in flat nano - channels of the width of the order of 10 molecular diameters and with vibrating walls. Both cases of crystalline and amorphous walls are considered. It is shown that these vibrations have an essential influence on the structure and the flow of the fluid. In particular, the vibrations of the walls with crystalline structure strongly enhance a positional order in the fluid and give rise to significant changes in the fluid flow rate.
It is shown that a fluid flow through the flat nano-channel can be efficiently controlled by high frequency vibrations of one of the channel's bounding wall.
