WebDec 6, 2024 · Generalized Darcy's law for parity odd three-dimensional fluids. A Hele-Shaw cell is a device used to study fluid flow between two parallel plates separated by a small … Darcy's law is an equation that describes the flow of a fluid through a porous medium. The law was formulated by Henry Darcy based on results of experiments on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences. It is analogous to Ohm's law in electrostatics, linearly relating the volume flow rate of the fluid to the hydraulic head difference (which is often just proportional to the pressure difference) via the hydraulic conductivity.
