Reply To: Is this a mistake in Fluent formulations in porous media?

[Dino]

Thank you for the help. The second one is from the ANSYS Fluent User Guide version 2021 R1 while the first is from ANSYS Fluent User Guide version 12.0. Both versions are discussing the physical velocity formulation. I am just trying to figure out what shape of equations Fluent uses for both superficial and physical velocity. If version 2021 R1, why the source term in the momentum equation has porosity^2 and porosity^3 for the first two terms instead of porosity and porosity^2; for physical velocity?
