摘要： 管流是指单根“管子”中的流动,渗流是指多孔介质中的流动,多孔介质是由大量的“管子”组成的,渗流过程也是由管流来实现的,因此,管流与渗流是完全统一的,管流公式与渗流公式也是完全相通的。管流公式适用于“管子”数目少、且管径便于测量的情形,而渗流公式适用于“管子”数目多或“管子”数目少但管径不便测量的情形。实际应用时,应根据具体的情形选用相应的公式。

关键词: 多孔介质, 管流, 渗流

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
