在工程系统中遇到的冰成核通常是由固体/水界面引起的。当经典成核理论被用来分析在这样的系统中的冰成核,界面的均匀性,有助于冰成核必须仔细考虑,因为经典成核理论不能直接应用于非均匀的界面。在这项研究中,讨论的固体/水界面的冰成核活性的均匀性,在玻璃表面上制备的水滴中的冰成核进行了研究,从微米到亚毫米的各种液滴尺寸。当水与玻璃表面之间的界面面积小于1 × 10− 10 m2时,冰核温度显示出约2 °C的分散性,表明界面的均匀性。但当界面面积大于1 × 10− 8 m2时,冰核温度出现较大的离散性,表明冰核活性不再均匀。
Ice nucleation encountered in engineering systems is often induced by solid/water interfaces. When classical nucleation theory is used to analyze ice nucleation in such systems, the uniformity of interfaces that contribute to ice nucleation must be carefully considered, because classical nucleation theory cannot be directly applied to non-uniform interfaces. In this study, to discuss the uniformity of ice nucleating activity of solid/water interfaces, ice nucleation in water droplets prepared on glass surfaces was investigated for various droplet sizes from micrometer to sub-millimeter. When the interfacial area between water and the glass surface was smaller than 1 × 10−10m2, the ice nucleation temperature showed scatter of about 2 °C, suggesting uniformity of the interface. However, when the interfacial area was larger than 1 × 10−8m2, the ice nucleation temperature showed large scatter, suggesting the ice nucleating activity was no longer uniform.
