The rheological properties (yield stress, storage modulus) of a series of high internal phase ratio oil-in-water emulsions were investigated using a controlled-stress rheometer. The volume fraction of the dispersed phase ranged from 0.7124 to 0.8961. The yield stress for any given emulsion was determined from three different experiments: steady shear, oscillatory shear, and creep/recovery experiments. The yield stress values obtained from different experiments show good agreement with each other. Both yield stress and storage modulus of the emulsions increase with the increase in the dispersed phase concentration. The Princen and Kiss equations are used to interpret the yield stress and storage modulus data of this study.
