Solute diffusion
Extends from Icons.Diffusion, Interfaces.OnePort (Partial transfer of solute between two ports without its accumulation).
Information
The diffusion conductance parameter can be estimated using the Fick's laws of diffusion:
J= -D*(dPhi)/dx
where
J is molar flow of solute per area [mol/(m2.s)].
D is diffusion constant [m2/s].
dPhi is concentration gradient [mol/m3].
dx is length of diffusion [m].
The solution on both sides must have the same properties (for example solubilities, chemical activities, osmolarities,...)!
