WebAbstract. Darcy's law for anisotropic porous media is derived from the Navier-Stokes equation by using a formal averaging procedure. Particular emphasis is placed upon the proof that the permeability tensor is symmetric. In addition, it is shown that there is a one-to-one relationship between the local and macroscopic velocity fields. WebJan 16, 2016 · Darcy’s law is based on the experimental observation that the apparent fluid velocity is proportional to the applied pressure gradient on a porous medium. This observation is analogous to the flow of fluid through pipes and capillaries (Poisseuille’s law) and also to that of the flow of current through a resistive conductor.
