文摘

The relationship between phase fractions and pressure gradients in multiple emulsions is quantified. A method to determine the disperse phase fraction is developed and presented. Based on the measured disperse phase fraction, the encapsulation efficiency is determined. The formation of compressed multiple emulsion during production is analysed.
