Carreau model implementation

Postby shubh_shinde » 14 Oct 2017, 17:11

Dear all,
Can anyone suggest how to implement the Carreau-Yasuda model in elmer. I have provided all the parameters required by the solver except for the viscosity. In the elmer models manual it says relationship between stress and strain velocity should be provided.
I do not understand how to input this to model. Please suggest.
Thank you,
Shubham

Hi Shubham,
The following discussion may provide you a starting idea for applying non-newtonian material models in N-S equations.
