By using spatial averaging methods, in this work we derive a Darcy's-type law from a fractional Newton's law of viscosity, which is intended to describe shear stress phenomena in non-homogeneous porous media. As a prerequisite towards this end, we derive an extension of the spatial averaging theorem for fractional-order gradients.

WebDarcy's Law 2-7 The lower limit of Darcy's law is associated with extremely slow groundwater movement. In such cases, other gradients, such as thermal, chemical and/or electrical, may be stronger than the hydraulic gradient and may control the movement of flow.
