Carmen-Kozeny equation, permeability

Liu and Civan propose that absolute permeability reduction can be attained through the modification of the Carmen-Kozeny equation. [Pg.367]

The permeability of swollen gel layers of superabsorbent polymers can be expressed by the Carmen-Kozeny equation, which is based on the Darcy equation when the porosity and surface area are to be considered ... [Pg.908]

The fineness of a powder can be studied with the help of permeability techniques, in which the resistance to fluid flow of a powder plug is measured and the fineness of the powder deduced from this measured resistance using various equations such as the Kozeny-Carmen equation. The interpretive equations used to calculate the surface area from permeability measurements make several assumptions concerning the pore structure of the packed powder bed, and the... [Pg.2591]

The Kozeny-Carmen equation for deriving the coefficient of permeability also takes the porosity, n, into account as well as the specific surface area of the porous medium, Sa. that is defined per unit volume of solid... [Pg.166]
