Article Snippet: A uniform pressure drop at the inlet was assumed, and the COMSOL Multiphysics ® (version 5.3) CFD code was used to solve the incompressible continuity and Stokes equations in the pore space geometry of the CFFs. (2) ∇ P = μ ∇ 2 u + F (3) D ρ D t = − ρ ∇ . u where P is the pressure force (Pa), µ i s the dynamic viscosity (kg/m∙s), u is the velocity vector (m/s), F indicates all forces other than the pressure, and ρ is the fluid density (kg/m 3 ).
