| Abstract: | A numerical method based on unstructured grids was proposed to simulate ice accretions on multi-element airfoils.The air flowfield was solved using the Euler equations.Based on air velocity distribution,the governing equations for droplets were solved using an iterative method to obtain the collection efficiency.The different freezing models corresponding to the rime and glaze ice were employed to simulate the freezing process.The process of ice accretions was simulated with the assumption that ice accumula... |
