... Poiseuille flow In micro/nanoscale gas flows, the small system dimensions mean that the nondimensional Knudsen number, Kn, defined as the ratio of the molecular mean free path (MFP) of the gas λ to a characteristic flow field dimension, indicates the flows are often rarefied. As Kn increases...
