multiPhaseEulerFoam + basicKinematicCollidingCloud + mixture viscosity

alvora · January 7, 2022, 08:27

Hi Foamer,

I am trying to couple multiPhaseEulerFoam with LPT library to simulate the micro size solid particles in the bubble column. I donot know whether this approach will work, but I would like to try.

To initialize the object of basicKinematicCollidingCloud in createFields.H, I need the velocity, density and viscosity of mixture fluids (carrier fluids). There is the fluid object of phaseSystem type, which has access functions for the mixture velocity and mixture density.
But, now I need the mixture viscosity. Can anyone help how can I access the mixture viscosity?

Any suggestions/comments are highly appreciated

kind regards

I'm doing this job, too. Would you share your experience with me? Thanks a lot.
