Icing is a phenomenon by which super-cooled droplets impinge on a solid surface and accrete on it. Many studies on ice accretion have been conducted because icing phenomena cause serious aviation problems in various situations. Since there are many unknown physical properties of the super-cooled droplets, a detailed freezing process of super-cooled droplets has not been clarified yet. In our previous study, the static freezing process of super-cooled droplets of water was reproduced by numerical simulation. In this study, the dynamic freezing process is simulated in the case where a super-cooled droplet impinges on a flat plate in air. The obtained results indicate that our numerical method can reasonably reproduce the behavior of droplet freezing along the interface between the water and air.
