Abstract

Phase inversion in liquid-liquid dispersions corresponds to the transitional boundary between Oil-in-Aqueous dispersion and Aqueous-in-Oil dispersion. A theoretical model based on simple assumptions was proposed to predict phase inversion point, ambivalence region and the hysteresis effect of inversion. Experimental data from the literature were used to validate the model and results were compared with those obtained by the Yeo et al. model. Comparison shows that there is a reasonable agreement between the suggested model and the experimental results taken from the literature. It is also pointed out that this model generates smaller relative errors than the previous work of Yeo et al. does.
