Kozeny-Carman equation

Correlations of this form can be rationalized from the Kozeny-Carman equation:

The resulting flow-rate of air through the bed yields the specific surface by the Kozeny-Carman equation:

Today he is mainly remembered for Kozeny-Carman equation of a fluid flowing through a packed bed of solids.

The Kozeny-Carman equation (or Carman-Kozeny equation) is a relation used in the field of fluid dynamics to calculate the pressure drop of a fluid flowing through a packed bed of solids.
