Dear everyone,
I have a problem understanding the fluid flux in triphasic material.
In the Theory Manual:
Equation.png
Eq.2.126,
k(solvent velocity- solid velocity) is related to the transient permeability, the gradient of effective pressure (first term in the parentheses), and the gradient of ion concentration. Physically, I understand effective pressure is the driven pressure and permeability determines how fast the fluid can transfer. How to understand the physical meaning of the second term in the parentheses? And under what condition, this term is important.
Thanks,
Bo
