摘要:

尽管经过数十年的研究,姆潘巴效应仍然对科学家构成挑战,促使人们进一步调查并完善现有假说。本工作使用热成像等光学工具,对水滴中的姆潘巴效应进行分析和研究。我们通过一个易于控制的实验,分析了时间以及接触角随温度的变化。本工作为围绕姆潘巴效应的持续讨论做出了贡献,强调了跨学科合作和实验严谨性对于揭示这一引人入胜现象复杂性的必要性。对姆潘巴效应的更深入理解不仅增强了我们对热力学和流体动力学的认识,还为低温保存、气象学和材料科学等领域的实际应用开辟了途径。

英文摘要:

Despite decades of research, the Mpemba Effect challenges scientists, prompting further investigation and refinement of existing hypotheses. This work uses optical tools such as thermography to analyze and study the Mpemba effect on drops. We analyze times and contact angle changes with temperature with an easily controlled experiment. This work contributes to the ongoing discourse surrounding the Mpemba Effect, emphasizing the need for interdisciplinary collaboration and experimental rigor to unravel the complexities of this intriguing phenomenon. A deeper understanding of the Mpemba Effect enhances our knowledge of thermodynamics and fluid dynamics and opens avenues for practical applications in fields such as cryopreservation, meteorology, and materials science.
