A New Extensional Viscosity Model Based on the Cross Model for Polymer Fluids

Abstract:

A new extensional viscosity model based on the Cross model is introduced. The proposed model can correctly describe the relation between extensional viscosity and extension rate. Effect of the four parameters in the new model is analyzed in detail. Compare the predictive curves to the measurement results reported in the references. It shows that the model calculation gives a good fit to the experiment data. This simple model has only a few parameters and is easy to use.
