The present paper research has realized the validation of a mathematical model applied for the prediction of rheological behavior of the complex emulsions type W/O water 30%-crude, refined rapeseed oil 70%. The rheological behavior were investigated for the emulsions realized with two types of industrial oils: C1 and C2 - crude and refined rapeseed oil with different physical-chemical composition: 892 ppm phospholipids content, 1.09 FFA-index, 0.18% moisture, impurities insoluble in solvents 0.12% for C1; 50 ppm phospholipids content, 0.10 FFA-index and 0.020% moisture for C2.
The mathematical model for the emulsions rheological behavior prediction was correlated with the composition of the complex emulsions W/O with crude and refined rapeseed oils.
The parameters of the mathematical model were identify by the inverse analysis method based on the experimental rheological data values and were realized the validation of the theoretical mathematical model.
