Hi,
I am attempting to model inkjet ejection of viscoelastic polymers through a nozzle via OpenFOAM. However, my question is more general. I have complex rheology experimental data (G*, G', and G'') as a function of frequency; and I would like to fit this data to the Phan-Thien-Tanner (PTT) model or Maxwell viscoelastic model. However, I am unsure how to perform this fitting and whether or not it is possible to convert experimental rheology data directly to a model fit? Any advice would be greatly appreciated. |
