Basic Laws of Single-Phase Flow

All fluids with particles in the molectrlar range (atoms, ions, molecules) can be described by laws valid for one-phase flow. [Pg.118]

Darcy s law (Darcy, 1856) is a phenomenological law that is valid for the viscous flow of a single-phase fluid (e.g. groundwater flow) through porous media in any direction. This basic law of fluid flow is a macroscopic law providing averaged descriptions of the actual microscopic flow behaviour of the fluids over some representative elementary volume of the porous medium. For isothermal and isochemical subsurface conditions, the law can be written as (Hubbert, 1953)... [Pg.5]

Flow through a porous medium is described by Darcy s law, which, in its basic form, is only valid for a single flnid flow and was extended to a second fluid by Wyckoff Botset (1936). This yields equation 10 for the flow velocity of the fluid and gas phase, respectively. [Pg.295]
