An Eulerian method to simulate aircraft icing was developed based on two-phase flow theory

and the water collection efficiency and impingement limits were solved based on the velocity distribution of air flow. Results show that Eulerian method performs better on water collection efficiency and impingement limit than Lagrangian method

especially under large median volumetric diameter conditions. The predicted ice shape and surface temperature were compared with experimental results

the thickness error of the cylinder ice shape was less than 15.0% and the computational results were in good agreement with the experiment data

showing that the icing model and two-phase flow simulation are feasible and effective.
