摘要:

针对飞机地面除冰作业中多物理场耦合机制复杂、除冰液喷洒参数缺乏理论指导的问题,提出一种基于相场法与Realizable k-ε湍流模型的倾斜射流机翼表面流动传热仿真模型。实现了对射流冲击、液膜流动及非稳态传热全过程的数值重构。基于该模型,深入探究了射流角度对冲击动量分配及传热特性的调控机制。仿真结果揭示了不同射流角度下流动与传热特性的演变规律:15°射流能产生最大的法向冲击压力,适用于破碎高附着力坚冰;45°射流实现了动量向切向铺展的最佳转化,液膜流速最高,兼顾了冲击力度与除冰液覆盖效率;60°射流虽因卷吸效应导致空气段温度损耗增加,但显著扩大了高努塞尔数的覆盖范围,更适用于除冰后的防冰液保持阶段。该数值模拟研究为实现飞机地面除冰的精细化作业提供了理论支撑。

Abstract:

To address the complex multiphysics coupling and lack of theoretical guidance for spray parameters in aircraft ground de-icing, a simulation model based on the Phase-Field method and Realizable k-ε turbulence model is proposed to investigate inclined jet flow over airfoil surfaces. The model enables the numerical reconstruction of jet impingement, liquid film flow, and unsteady heat transfer processes, providing a framework to elucidate the regulatory mechanisms of jet angles on momentum distribution and thermal characteristics. The simulation results reveal distinct variations in the flow and heat-transfer characteristics at different jet inclination angles. At a jet angle of 15°, the maximum normal impact pressure is generated, making this condition more suitable for breaking strongly adhered ice. At 45°, the most effective conversion of jet momentum into tangential spreading is achieved, and the highest liquid-film velocity is obtained, thereby providing a favorable balance between impact intensity and de-icing fluid coverage efficiency. Although greater temperature loss in the free-jet region is induced at 60° because of the enhanced entrainment effect, the surface area characterized by high Nusselt numbers is significantly enlarged, making this condition more suitable for maintaining anti-icing fluid coverage after de-icing. The numerical results provide a theoretical basis for the refined optimization of aircraft ground de-icing operations. This research establishes a theoretical foundation for precision aircraft ground de-icing operations.
