Rheology of structured liquids. Flow regimes and rheological equations

A system of rheological equations is presented, obtained on the basis of structural-kinetic representations, which describes viscous and elastic properties of structured liquids, namely concentrated suspensions, emulsions, micellar solutions, solutions and polymer melts. The structural model equations hold for equilibrium steady-state flow and for equilibrium oscillating flow. The equations are suitable for approximating rheological curves , , , , at individual intervals of shear rate or oscillation frequency. Each such interval corresponds to a certain state of the structure. As an example, the results of approximation of shear viscosity curves for polymer solution, micellar solution and emulsion are given.
