摘要

Ice crystal growth problem have attracted special attention due to in heat transfer deterioration and pump power consumption increasing, by adding very small amount of suitable additives can control the ice crystal growth. This paper investigates ice crystal growth in isothermal condition when adding four different additives, and then calculate the energy between surfactants and ice crystal to explain the effect of different additives. The results indicate that the interaction is Coulomb interaction and Van der Waals interaction for anionic and nonionic surfactant respectively. This method provides a method to explore the mechanism of controlling ice crystal growth with surfactant.
