Gas Flow in Nanochannels

Gas flow in nanochannels is distinguished by the regime when a characteristic size of a channel is comparable with the mean free path of gaseous molecules.

However, for Knudsen numbers higher than unity, as it could be the case in nanochaimels (gas flow in nanochannels) or in low-pressure flows in microchannels, the continuum approach is no longer valid, and molecular methods such as the Direct Simulation Monte Carlo - DSMC - (Monte Carlo method) or the Lattice Boltzmann methods (Lattice Boltzmann method) should be used.
