Polyflow: non-Newtonian fluid with large slip velo

Daniel Suasnabar

Hi dear all,

Anybody with polyflow experience and modelling generalized Newtonian and viscoelastic flows where the slip velocity is dominant?. I've got a material which is close to a solid but our current model is fluid. Characterization of this material (fiber cement) for modelling purposes from a solid point of view is becoming complex so the model. But one of the major problems I found is modelling the slip at the walls, particularly when the slip is very dominant.

Thanks for any help

Daniel
