Abstract:

In this paper, nonequilibrim molecular dynamics (NEMD) was used to simulate liquid flow in microchannels with ‘lotus effect’ coating. Without considering atomic structure and long-range interaction, we have been dedicated in establishing a two-dimensional geometric model based on the coating and studying the behavior of liquid near the inner surfaces of ‘lotus effect’ microchannels. The shape of a single pattern in the coating and the thickness of one microchannel were varied to study the influences of these parameters on velocity profile of liquid in the flow direction, the maximum of this velocity, and its position perpendicular to flow direction. The proper conditions which made the velocity slip of liquid near the boundary layer of microchannels maximum and liquid move most fast were decided.
