Features of Modeling Heat and Mass Transfer Processes during Ice Formation in Conditions of an Atmospheric Cloud Consisting of Supercooled Droplets
摘要
An improved icing model is proposed, which makes it possible to enhance the accuracy of three-dimensional calculations of the icing process on various aviation equipment elements. The model was verified based on the results of calculations using the Ansys Fensap-Ice and Flow vision software packages. In the process of validating the model using available experimental data, the correctness of the calculation methods used in modeling heat and mass transfer processes occurring on the surface of ice buildup was demonstrated. Using model objects as an example, the advantages of the proposed model for calculating complex forms of ice buildups that arise in real icing conditions, including icing conditions with large supercooled drops (ice frost) are shown.
