Hi everyone,

I would like to analyse flow of polymer solution in an enclosed system.

*System has inlet and outlet.
*Polymer solution is made by mixing 5 g solid in 100 g solvent. So, solid content of solution is %5.
* Polymer solution is non-newtonian liquid,
* Shear thinning occurs at low shear rates,
* Shear rate of the flow is low, flow exit velocity is about 1 m/s.
* Flow temperature is constant at about 20 C.
* At this temperature, more or less, STORAGE elastic shear modulus is larger than LOSS shear modulus. So, the flow has gel-state characteristics.
* At this temperature, viscosity range of solution is 100-250 Pa.s. viscosity changes with shear rate.

How can I model such characteristics of polymer solution in Ansys Fluent like CFD simulation package ? Which material model is applicable ?
