摘    要:利用计算流体力学(CFD,Computational Fluid Dynamics)软件FLUENT,对二维机翼在结冰气象条件下飞行时的水收集系数,以及防冰系统工作并达到稳定后的防冰表面温度进行了计算.水收集系数计算采用FLUENT中的欧拉两相流模型以及用户自定义函数.特定飞行条件及热气防冰系统结构下的防冰表面平衡温度分布预测采用防冰腔内外热流耦合的方法.所得结果和理论分析一致,表明了利用FLUENT可以有效的进行防冰研究,包括水收集系数及防冰表面温度的预测,为今后进一步研究设计热气或电热防冰系统打下基础. 

关 键 词:飞机防冰   水收集系数   表面温度

Abstract:Computational fluid dynamics(CFD) software toolkit FLUENT was used to predict the droplet collection efficiency and anti-icing surface equilibrium temperature on two-dimensional airfoils when the ice protection system was in operation.Collection efficiencies were obtained using the Eulerian multiphase model,implemented through user-defined functions in FLUETN.The surface equilibrium temperature distribution in responding to certain flight condition and the hot-air inlet configuration was predicted by an integrated airfoil leading-edge interior-exterior thermodynamic analysis.Some examples and validation studies were presented.The numerical results are acceptable and consistence with the theory analysis.The presented research work indicates a validity of using FLUENT in studying aircraft anti-icing,including prediction of water collection efficiency and temperature distribution on anti-icing surface,which are useful for future study in design of aircraft hot-air anti-icing system.
Keywords:aircraft anti-icing  collection efficiency  surface temperature
