Two common models used to fit experimental non-Newtonian data are the Cross model and the Carreau-Yasuda model. The Cross model is an empirical equation that is used to fit non-Newtonian data (Cross, 1979). The Cross model can describe many types of fluids including dispersions, polymer melts, and polymeric solutions.
