摘要
基于液/固相变的基本理论,对飞机结冰过程中冰层和液膜的传热特性进行了研究,建立了考虑固/液相区传热特性及固/液、气/液界面同时移动条件下的传热模型,并采用该模型对飞机结冰过程中的冰层和水膜生长特征进行了分析。研究表明,所建模型考虑了固、液相区的传热过程及液/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。
Heat transfer characteristics in aircraft icing are studied based on the theories of liquid-solid phase change. A model including heat transfer in a solid and liquid region and the moving interfaces is established. The growth of ice and water is analyzed. The results indicate that the icing accretion is not only influenced by the airflow parameters but also influenced by the inner heat transfer of each phase. With the current model we predict the accretion rate and type of ice relatively well in consideration of the heat transfer process and the nonlinear characteristics of liquid-solid phase change.
