Abstract

This study explores the intricate heat transfer dynamics and thermographic patterns during the phase change from supercooled liquid water to ice. Using high-resolution, high-speed infrared thermography, real-time temperature data were captured during the freezing process. The resulting temperature profiles reveal critical insights into the freezing dynamics, particularly highlighting the rapid phenomena of recalescence in supercooled conditions. Notably, this study represents the first time recalescence, a rapid and previously elusive phenomenon, captured and documented in the scientific literature. Additionally, a mathematical model is developed to describe the recalescence phase on macro scale. These findings have practical relevance for various industries, aiding in the design of more efficient anti−/de-icing technologies, refrigeration systems, weather prediction models, and cryopreservation techniques. The study also opens new avenues for further exploration in understanding phase transitions in supercooled water.

通过高速红外热成像探索冻结过冷水滴中的热传递

这项研究探索了从过冷液态水到冰的相变过程中错综复杂的传热动力学和热成像模式。利用高分辨率、高速红外热成像技术，在冷冻过程中采集了实时温度数据。由此获得的温度曲线揭示了冷冻动力学的重要见解，尤其突出了过冷条件下的快速再凝聚现象。值得注意的是，这项研究首次在科学文献中捕捉和记录了再凝聚这一以前难以捉摸的快速现象。此外，还建立了一个数学模型来描述宏观尺度上的再凝聚阶段。这些发现对各行各业都有实际意义，有助于设计更高效的防冰/除冰技术、制冷系统、天气预测模型和低温保存技术。这项研究还为进一步探索了解过冷水的相变开辟了新途径。

期刊介绍： Cold Regions Science and Technology is an international journal dealing with the science and technical problems of cold environments in both the polar regions and more temperate locations. It includes fundamental aspects of cryospheric sciences which have applications for cold regions problems as well as engineering topics which relate to the cryosphere. Emphasis is given to applied science with broad coverage of the physical and mechanical aspects of ice (including glaciers and sea ice), snow and snow avalanches, ice-water systems, ice-bonded soils and permafrost. Relevant aspects of Earth science, materials science, offshore and river ice engineering are also of primary interest. These include icing of ships and structures as well as trafficability in cold environments. Technological advances for cold regions in research, development, and engineering practice are relevant to the journal. Theoretical papers must include a detailed discussion of the potential application of the theory to address cold regions problems. The journal serves a wide range of specialists, providing a medium for interdisciplinary communication and a convenient source of reference.
