This paper presents the numerical analysis of the deformation of a droplet impinging upon a cold flat surface. The calculation was based on the basic equation of the SMAC method in the cylindrical coordinate, under the consideration of the surface tension. When Re, Fr and We numbers are the same, the experimental results are in good agreement with the calculated ones at each non-dimensional time. The heat transfer model was constructed for the case of impingement upon a hot surface, and the basic equation were solved by the energy method, one-dimensional heat condition, and two-dimensional heat condition. The experimental results of the life time of a droplet agree well with the calculated ones, as shown by the latter two methods. It is quite possible to simulate the temperature profile in the droplet, although the convection in the droplet and the evaporation process are disregarded in the model.
