Outline
The phenomenon of icing on the surface of superstructure of ships and marine structures is the result of a large number of water droplets impacting on the cold wall surface to form a water film and then accumulating ice. And surely, at a high wind speed more water droplets often collide with vertical structures. The movement and freezing behaviors of water droplets can have a significant effect on the icing process and final icing shape on the surface of the structures. Based on the VOSET gas-liquid interface tracking method coupling with VOF and Level-Set, and Enthalpy-Porosity phase change method, a unidirectional coupling model between water droplets and isolated cold plate was established using the large coefficient method. Simulation of the freezing process of a single water droplet impacting an isolated cold plate was achieved, and the phenomenon of the air entrainment was reproduced. The effects of factors such as water droplet velocity, component surface wettability on the freezing process were analyzed. The process of multiple water droplets impacting a vertical structure surface to form a liquid film and freeze was further simulated. The relevant results can provide technical support for the prediction of the typical component surface icing of superstructure and the study of anti-icing and de-icing methods.
