Definition of specific flow law in OpenFoam

sidemountyucatan · April 13, 2022, 07:39

Hi,

for exercise purpose I want to define a specific flow law in an openFoam case. E.g. Ostwald-de-Waele, Bingham etc.. How can I do this ? Could somebody give me a useful description ?

As solver I would use simplefoam for the first steady state simulation because its a incompressible case.

Thx a lot !

Hi,

You can choose several viscosity models in transportProperties.
Have a look in the user guide: https://cfd.direct/openfoam/user-gui...#x38-2860007.3

Cheers,
Yann
