微过冷却水滴在固体表面的冻结行为

Micro-droplet freezing on a solid surface under atmospheric conditions

对10-50μm直径的微过冷却水滴,在温度为-10-0℃、85%相对湿度下的工况以及二维T型热电偶表面的冻结过程进行了试验研究.研究结果表明,完全冻结时间受到液滴直径和环境温度的影响较大.

Icing formations of micro-droplet with diameter of 10～ 50 μm on a T-type thermocouple cured into a 2-D flat surface were experimentally studied under the-10～0 ℃ air temperatures and 85%air relative humidity in this paper.It is found that the total freezing time was affected by the micro-droplet diameter and the air temperature.
