LUID FLOWS IN NARROW CHANNELS

摘要

We present the results of some Direct Monte-Carlo Simulations of a simple, monoatomic gas flows and also some Molecular Dynamics simulations of the flows of water through very narrow channels (plane Poiseuille flows). The main conclusion from the results is that the roughness of the walls of such narrow channels, even if it is of molecular size, influences very strongly the flow of water, introducing large velocity fluctuations and sometimes even stopping the flow.
