| 中文摘要: |
| 目的 通过实验室模拟不同环境条件的降雨试验，研究金属材料表面的积冰行为。方法 基于数值仿真分析，选择适合积冰的放置方法，针对金属材料开展降雨环境模拟试验。以水温、环境温度、试件温度、喷淋高度、试件厚度为基本参数，分析实验室模拟降雨环境下不同金属材料表面的积冰程度。结果 仿真分析可以得到理想状态的理论分析结果。当水温为5 ℃，环境温度为–1.5、–3 ℃时，在高度3、4 m喷淋30 min后，除10 mm厚度7075铝合金外，被试材料积冰均难以达到6 mm。当水温不变，环境温度为–6 ℃时，在高度3、4 m喷淋30 min后，部分被试材料达到6 mm积冰。当试验环境温度不变而水温降低时，水温与积冰呈较明显的递增趋势。在其他试验条件相同的情况下，环境温度为–9 ℃时，所有被试材料积冰均达到6 mm以上。结论 调整各项试验环境参数可控制金属材料表面的积冰程度。在相同水温、喷淋高度和材料厚度的条件下，随着环境温度的降低，积冰增加，4 m喷淋高度的积冰优于3 m喷淋高度。可将试验数据与理论分析数据相融合，使用理论分析结果进行方向预测，利用环境模拟试验数据对其进行修正。 |

| 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. |
