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 ? Regards |
