KozenyCreny
KozenyCreny is a theoretical concept used in fluid dynamics and porous media physics. It refers to a specific mathematical model that describes the flow of fluids through a porous material. The Kozeny-Creny equation, also known as the Kozeny-Carman equation or Kozeny-Fries equation, is a widely used empirical relationship that relates the pressure drop across a packed bed of granular material to the superficial velocity of the fluid flowing through it.
The equation is derived by considering the porous medium as a bundle of tortuous capillary tubes. It
The Kozeny-Creny model is particularly useful for estimating the permeability of a porous medium, which is
