Darcy - by itself - refers to a porous system at the macroscopic scale; and it emphasizes strongly that we are NOT supposed to look at the details - even - at the microscopic-scale.
Given this background, Is it fair to use the term "nano-Darcy"?
We would like to work or we are required to work at the nano-scale - in a porous medium, while, following Darcy's law - by default - has become a belief - without considering the "scale" at which we would like to work at.
Nano and Darcy - can never - merge together - as far as I know.
Would be glad to receive technical comments.
Well,
For example, dispersion coefficient depends on the velocity of the fluid, including Darcy velocity in general. Based on this, how we can understand the movement and velocity of liquids between the cells of living organisms, the movement will certainly be smaller than what is known as nanostructures. The idea is only debatable.
Sincerely
