| Abstract: |
| The work aims to study the ice accretion on the surfaces of metal materials by simulating rainfall experiments under different environmental conditions in the laboratory. Based on numerical simulation analysis, a suitable placement method for ice accretion was chosen and simulated rainfall experiments were carried out to metal materials. Then, water temperature, ambient temperature, test material temperature, spray height and test material thickness were considered as the basic parameters to analyze the ice accretion behavior on surfaces of different metal materials under simulated rainfall environments. Through simulation analysis, theoretical analysis results under ideal conditions were obtained. When the water temperature was 5 ℃ and the ambient temperature was–1.5 ℃and –3 ℃, the ice accretion of the test material except for the 7 075 aluminum alloy with a thickness of 10 mm was difficult to reach 6 mm after spraying for 30 min at a height of 3 m or 4 m. When the water temperature was constant and the ambient temperature was –6 ℃, the ice accretion of the test material could reach 6 mm after spraying for 30 min at a height of 3 m or 4 m. When the experimental environment temperature was constant, but the water temperature decreased, the water temperature and ice accretion showed an obvious increasing trend. When other experimental conditions were the same, but the ambient temperature was –9 ℃, the ice accretion of the all test materials could reach more than 6 mm. By adjusting various environmental parameters of the experiment, the ice accretion on the metal material surfaces can be controlled. Under the same water temperature, spray height and material thickness, with the decrease of ambient temperature, the ice accretion increases, and the ice accretion at a spray height of 4 m is better than that at 3 m. The experimental data can be combined with the theoretical analysis data, and the direction can be predicted by theoretical analysis results and corrected by the experimental data of simulated environment. |
