热力学现象是制约飞机结冰特性的重要现象之一。开展飞机结冰过程热力学行为的研究旨在深入把握结冰过程的规律特征,从而为建立科学有效的结冰防护手段、保障结冰条件下的飞行安全奠定基础。本文回顾和介绍了飞机结冰热力学研究所涉及的过冷水滴存在的物理机制、结冰热力学条件、形核与晶体生长、耦合液/固相变的复合传热传质特性,以及热力学效应作用下的结冰物理特性等相关领域的研究进展及发展现状,并基于国外相关研究的发展趋势,提出了中国未来飞机结冰热力学研究需重点关注的方向。

Thermodynamic phenomenon is an important phenomenon in aircraft in-flight icing process.Research on the thermodynamic behavior of aircraft icing will be beneficial for an accurate understanding of the freezing characteristic and physical mechanism of icing process,and will thus lay the foundation for the development of effective means for anti-icing and deicing to ensure flight safety in icing conditions.For over half a century,researchers have been aimed at lessening the hazards of aircraft in-flight icing.The current research and development in thermodynamic behavior of aircraft icing,including the physical mechanism of supercooling of water,thermodynamic conditions of icing,nucleation and crystal growth,and coupled liquid/solid phase transition of complex heat and mass transfer characteristics are reviewed,and the outlook and future efforts for research on thermodynamic behavior of icing is presented.
