摘要：

The supercooled droplet impingement on complicated icing surface has been investigated with the Eulerian method. A simplified air/droplet two-phase model is established, and an effective algorithm is proposed to deal with the dilute, weakly coupled air/droplet flows for aircraft icing problem. An Eulerian droplets computation code has been developed and validated with the iced NACA23012, and the results agree well with the experimental data. Meanwhile, compared with the results from the traditional Lagrangian method, it indicates that the Eulerian method gives a better prediction when the multiple impingement zones occur on complicated icing surface.
