I'm checking the theory of the Brinkman equation in the manual. There's a term I don't understand where stems from: 2/3nu(nabla u). I also checked the given references but this term is not metioned. Any clue?
Hi,
It's a viscous term which comes with the gradient of u and the transpose gradient.
In the classic Navier Stokes equation this term disappears because the divergence of u is zero.
Is it clear now?
