Structural rationale of a non-Newtonian flow

Abstract

The complex rheological behavior of structured systems, namely, suspensions, emulsions, polymer melts and solutions, micellar fluids, and liquid crystalline systems is analyzed. The behavior of such systems is characterized by the coexistence of different flow regimes in a wide range of shear rates. It is shown that the generalized flow equation (GFE) effectively describes plastic and pseudoplastic flow systems. The Newtonian and non-Newtonian behavior of structured flowable systems is explained within the structural microrheological model.
