Knudsen flow — describes the movement of fluids with a high Knudsen number, that is, where the characteristic dimension of the flow space is of the same or smaller order of magnitude as the mean free path. Separation processes using Knudsen Flow For a gas… … Wikipedia
Knudsen number — The Knudsen number (Kn) is a dimensionless number defined as the ratio of the molecular mean free path length to a representative physical length scale. This length scale could be, for example, the radius of a body in a fluid. The number is named … Wikipedia
Knudsen gas — A Knudsen gas is a model for gases where particle collisions are ignored, as opposed to the Lorenz gas where collisions are considered. In these gases the distance between molecules are bigger than the recipient where the gas is contained. A flow … Wikipedia
