Unification of Flow Equations in Tubes and in Porous Media

Abstract

Abstract: Flow can take place in tubes or in porous media. The porous media consist of bundles of tubes, so the flow in porous media is also finished through flows in tubes, namely, flow in tubes should be the same as flow in porous media. The equations for these two flows can be derived from each other. Tubular flow theory can be used for the situation of a certain number of tubes, in which the tube diameter can be easily measured. The theory of flow in porous media can be used for the situation of enormous tubes, or the situation of a certain number of tubes but the tube diameter being immeasurable. In practice, one of two kinds of flow theories can be chosen for a specific situation.

Key words: porous media, tube, percolation
