Hello

I am trying to model bubble column reactor having a non-Newtonian liquid as primary phase and air. I have used shear dependent non-Newtonian power law model. I want to find the apparent viscosity of the liquid.

1) Would like to know whether the molecular viscosity that Fluent determines is the same as the apparent viscosity.
I checked the contour plot of the molecular viscosity for the liquid and the mixture in my simulation. But, I found that the upper and lower limit of the viscosity range for the liquid is always equal to the maximum viscosity that I entered while defining the fluid. Also, the viscosity range for the mixture, however, shows the range I defined initially. That is, mixture viscosity values are giving me results expected for the liquid. I am confused with this result.

2) Even the shear rate (strain rate in fluent) is not within the expected range (i.e, based on the non-Newtonian power law formula).

Kindly help.

thank you
