  2. Darcy's law - Wikipedia

    en.wikipedia.org/wiki/Darcy's_law

    Darcy's law is an equation that describes the flow of a fluid flow trough a porous medium and through a Hele-Shaw cell.The law was formulated by Henry Darcy based on results of experiments [1] on the flow of water through beds of sand, forming the basis of hydrogeology, a branch of earth sciences.

  3. Darcy's law for multiphase flow - Wikipedia

    en.wikipedia.org/wiki/Darcy's_law_for_multiphase...

    The Darcy velocity is not the velocity of a fluid particle, but the volumetric flux (frequently represented by the symbol ) of the fluid stream. The fluid velocity in the pores v a {\displaystyle \mathbf {v} _{a}} (or short but inaccurately called pore velocity) is related to Darcy velocity by the relation

    Henry Philibert Gaspard Darcy (French: [ɑ̃ʁi daʁsi]; 10 June 1803 – 3 January 1858) was a French engineer who made several important contributions to hydraulics, including Darcy’s law for flow in porous media.

  5. Talk:Darcy's law - Wikipedia

    en.wikipedia.org/wiki/Talk:Darcy's_law

    Darcy's law provides the relationship between the resistance of the porous material to fluid flow and the fluid velocity (averaged over the Representative Elementary Volume of the porous material). In other words Darcy's law is a parameterisation (valid for small Reynolds numbers) not the fundamental equation itself.

  6. Darcy (unit) - Wikipedia

    en.wikipedia.org/wiki/Darcy_(unit)

    The darcy is referenced to a mixture of unit systems. A medium with a permeability of 1 darcy permits a flow of 1 cm 3 /s of a fluid with viscosity 1 cP (1 mPa·s) under a pressure gradient of 1 atm/cm acting across an area of 1 cm 2. Typical values of permeability range as high as 100,000 darcys for gravel, to less than 0.01 microdarcy for ...
