Abstract

An Eulerian method to numerically simulate ice accretions on airfoils based on unstructured grids has been presented. The Euler Equations are employed to solve the flowfields of the airfoils. The governing equations for droplets are solved based on the velocity distribution of the airflow to obtain the collection efficiency on the airfoil surfaces. The different freezing models are employed to simulate the freezing processes of the rime and glaze ice in order to calculate the ice amount. The ice accretions on a NACA 0012 airfoil have been simulated and the comparison with the experimental data indicates that the simulated method presented is feasible and effective.
