基于液/固相变的基本理论,对飞机结冰过程的液/固相变传热特性进行了研究,建立了液膜及冰层生长的分析模型,并采用该模型对来流条件各参数对冰层生长特征及其速率的影响进行了分析.研究表明,在飞机结冰过程中,冰层生长速率及不同冰型的形成不但受来流参数的影响,而且与固、液相区的内部传热特性相关,因而考虑各相区的传热过程是提高冰层生长预测准确性的重要途径.所建模型考虑了液/固相变的非线性特征,对冰层生长速率及冰型特征有着较好的预测作用. Based on the basic theory of liquid / solid phase change, the liquid / solid phase heat transfer characteristics of the aircraft during icing are studied, and the analytical model of liquid film and ice growth is established. The model is used to analyze the parameters The results show that the growth rate of ice and the formation of different ice formations are not only affected by the flow parameters, but also with the growth of solid and liquid regions Therefore, considering the heat transfer process in each phase is an important way to improve the accuracy of ice growth prediction.The nonlinear model of liquid / solid phase transformation is taken into account in the model construction, and the ice growth rate and ice type Features have a good predictive effect.
