Relationship between the degree of supercooling and the amount of adsorption by a drop of two kinds of surfactant water mixtures including different molecules diameters

Abstract

In recent years, ice slurries have attracted attention in the field of thermal storage because of their high cooling efficiency and uniformity. Active control of the supercooling state is necessary for stable production of this ice slurry. Matsumoto focused on the effect of surfactants on the suppression of supercooling resolution and proposed a method to control the supercooling state. In this study, we will examine the effect of a mixture of nonionic and anionic surfactant solutions with different molecular diameters and the application of voltage on the average supercooling degree. We also examine the relationship between the amount of adsorption and the average supercooling degree.
