In this paper a numerical study comparing the impingement behaviour of a hollow droplet and an analogous continuous droplet onto a substrate is presented. In the impingement model the transient flow dynamics during impact, spreading and solidification of the droplet are considered. The results of droplet spreading and solidification indicate that the impact process of the hollow droplet on the substrate is distinctly different from an analogous continuous droplet. The hollow droplet results in counter liquid jetting during the impact process, larger solidification time for the splat, smaller and thicker splat as compared to the analogous continuous droplet.
