摘　　要：在超临界压力下,航空煤油的物理和化学性质都会产生一系列变化,因此传热计算模式必须要具备较高的精确性,以提升航空发动机的效率与安全性,而这需要开发出精度更高且性能优秀的耦合传热计算模型。研究了超临界压力下航空煤油的耦合传热计算模式,基于实验验证建立了理论模型,探讨了在极端条件下热物理行为的复杂性。首先介绍了传热理论的基本原理和适用于超临界条件的状态方程,随后详述了耦合传热模型的建立过程,通过对比实验数据对模型进行了验证和调整,最终形成一个既具理论深度又有实际应用价值的计算工具,为航空煤油在超临界状态下的传热分析提供了新的视角和方法。Under supercritical pressure,the physical and chemical properties of aviation kerosene will undergo a series of changes.Therefore,the heat transfer calculation model must have high accuracy to improve the efficiency and safety of the aeroengine.This requires the development of a coupled heat transfer calculation model with higher accuracy and excellent performance.This paper studies the coupled heat transfer calculation model of aviation kerosene under supercritical pressure,establishes a theoretical model based on experimental verification,and explores the complexity of thermophysical behavior under extreme conditions.First,the basic principles of heat transfer theory and the equation of state applicable to supercritical conditions are introduced.Then,the establishment process of the coupled heat transfer model is detailed.The model is verified and adjusted by comparing experimental data,and finally forms a model with both theoretical depth and Calculation tools with practical application value provide new perspectives and methods for the heat transfer analysis of aviation kerosene in the supercritical state.
