Study and modeling of the rheological properties of concentrated water-in-oil emulsions
- Mendeleev Univ. of Chemical Engineering, Moscow (Russian Federation)
Study of the rheological curves of concentrated water-in-oil emulsions indicates that such systems behave like non-Newtonian pseudo-plastic liquids. A number of mathematical models for rheological curves: Chong, Frankel-Acrivos, Ostwald-Weil, Bingham, Stainer, Ferry, Haven, Ellis, and Meter models are considered. The regions of the model adequacy for rheological curves of emulsions with different contents of the dispersed phase are determined. It was shown that only the Ellis model adequately describes the complete rheological curves of concentrated water-in-oil emulsions of the studied composition. Therefore, this model can be applied to the prediction of the viscosity values for emulsions with various phase ratios.
