Effect of Water Temperature on Ice Adhesion Strength Based on Nucleation Theory

Aircraft icing will affect flight safety and even lead to serious flight accidents. Studying the adhesion strength between icing and substrate can provide specific index requirements for the design of aircraft anti-icing and de-icing system. An experimental platform for measuring shear adhesion force is designed,which is used to measure the freezing adhesion force of the substrate at different initial temperatures of freezing water. The temperature changes of water/ice during freezing are collected,and the experimental phenomena are analyzed by nucleation theory,focusing on the effect of the initial temperature of frozen water on the adhesion strength. The results show that the increase of initial freezing water temperature will promote ice crystal nucleation and improve the adhesion strength.
