结冰与金属表面分离过程的数值模拟与实验研究
Numerical Simulation and Experimental Study on Process of Icing and Metal Surface Separation
摘要
Abstract
It is of great significance to optimize de-icing methods by studying the adhesion characteristics between icing and object surfaces,as well as mastering the separation process between them.Although nano-scale numerical simulations provide some insights into the icing separation process,they fail to fully capture the complexities of real-world icing phenomena.Hence,there is a need to investigate the macro-scale icing separation process.We have constructed a test bench capable of assessing icing adhesion in both the normal and tangential directions.By conducting experiments at different temperatures,we have obtained valuable data on the change in normal and tangential adhesion between icing icicles and metal surfaces.Moreover,we have introduced a macroscopic icing adhesion model and incorporated a constitutive model for the cohesion unit layer.This facilitates the numerical simulation of the separation process between icing and metal surfaces in Abaqus software.By validating simulation results with experimental data,we gain insights into the characteristics of icing adhesion and achieve a better understanding of the icing and metal sheet separation process.关键词
