Hi Calin,
the best two papers to look at are the following:
Baber, K., Mosthaf, K., Flemisch, B., Helmig, R., Müthing, S. and B.I.
Wohlmuth: *Numerical scheme for coupling two-phase compositional
porous-media flow and one-phase compositional free flow.* IMA Journal of
Applied Mathematics 77(6): 1-23.
<http://imamat.oxfordjournals.org/content/77/6/887.abstract>
Mosthaf, K., Baber, K., Flemisch, B., Helmig, R., Leijnse, T., Rybak, I.
and B.I. Wohlmuth: *A coupling concept for two-phase compositional
porous-medium and single-phase compositional free flow.* Water Resources
Research 47: W10522.

Unfortunately, the stabilization scheme is not described in sufficient
detail there. As you can see from the implementation, there are a lot of
technicalities involved. The basic idea is standard, namely, to add a
term alpha.div.grad.p to the mass balance. I hope that one of the two
papers above contains a reference to that basic idea. If not, tell me
and I will look it up.
We have not implemented a decoupled model for Stokes yet. This is
somehow on our agenda, but it will still need some time.
Kind regards
Bernd

Dear Dumux users,
I have two questions regarding the implementation of Navier-Stokes
equations in Dumux:
1.I found in Dumux the implicit solver using the box method and a
stabilization scheme for the (Navier-)Stokes problem. On the mailing
list archive, I found a discussion in 2012 about this implementation,
but I need to know the details of the stabilization scheme. Can you
indicate me a reference (thesis/article/web) describing the
stabilization scheme used in the implicit NS solver?
2.Has anybody already implemented in Dumux the DECOUPLED model for the
(Navier-)Stokes problem?
Best regards,
Calin
