摘要:

为了解决冰晶生成的技术难题,采用沿程冷却法对水滴相变成冰晶的过程进行了数值模拟,以确定冰晶生成的具体位置、范围,即进行冰晶结冰模拟试验的试验段区间。冰晶在随气流运动过程中会与周围空气发生热、质传递,其直径、温度和速度等参数变化显著。基于沿程冷却的方法,加入相变判断准则,研究了不同条件下冰晶沿程参数变化的规律。研究结果表明,冰风洞稳定段进口气流速度增加时,试验段内部的风速大幅增加。进口气流速度为10、15、20 m/s的条件下,试验段内部的结冰比例相对较高,均达到了90%以上。在进口气流温度为233.15 K和223.15 K时,水滴在x=2.3 m附近已完全冻结成冰晶。随着水滴直径的增加,试验段内部沿程不同截面上的总水含量逐渐降低,水滴开始结冰的位置沿运动方向向后推移。

Abstract:

In order to solve the technical problems of ice crystal formation, the process of water droplet phase turning into ice crystals was numerically simulated by the path cooling method to determine the specific location and range of ice crystal formation, that is, the test section range for conducting the ice crystal icing simulation test. In the process of moving with the air flow, the ice crystal will have heat/mass transfer with the surrounding air, and its parameters such as diameter, temperature and velocity change significantly. Based on the path cooling method and phase transition criteria, the variation of ice crystal parameters under different conditions is studied. The results show that when the inlet wind speed of the stable section increases, the wind speed inside the test section increases significantly. Under the conditions of inlet wind speed of 10, 15, 20 m/s, the icing proportion inside the test section is relatively high, reaching more than 90%. At ambient temperatures of 233.15 K and 223.15 K, the water droplets have completely frozen into ice crystals near x = 2.3 m. Furthermore, with the increase of the diameter of the water drop, the total water content in different sections along the test section gradually decreases, and the position where the water drops begins to freeze increases along the direction of movement.
