Non-monotonous behaviour of shear viscosity - Empirical modelling

Popis výsledku v původním jazyce

Practically all hitherto used empirical models used for characterisation of shear viscosity of liquids describe only its monotonous course. However, the onset of new materials is accompanied by more complicated characteristics of their behaviour including non-monotonous course of shear viscosity. This feature is reflected not only in an existence of one extreme point (maximum or minimum) but there can appear both extreme points; i.e. that shear viscosity initially exhibits shear thinning, after attaining a local minimum converts to shear thickening, and again after reaching a local maximum has a shear-thinning character. It is clear that for an empirical description of this complex behaviour a hitherto used number of parameters (four, five) in classical monotonous models (such as Cross or Carreau-Yasuda) is no longer tenable. If more parameters are applied, there should be given an emphasis on a relatively simple algebraic form of the proposed models, unambiguity of the involved parame
