Corrigendum to “Estimating the number of fingers and size of ejected droplets in droplet impingement processes on solid substrates”[Colloid Interface Sci. Commun. 50 (2022) 100651]

The splashing of droplets impinging on solid substrates includes complex behavior that is dependent on numerous factors, including the liquid properties, impingement velocity, and solid surface properties, such as wettability and roughness. Quantitative understanding of the behavior of the unstable liquid film during the splashing process remains elusive. Here we propose new models in which the number of fingers and the size of the ejected secondary droplets can be characterized taking into account the liquid film thickness and the wettability and roughness of the surface. The experimental data regarding the size of the secondary droplet and the number of fingers is found to be in good agreement with the predictions of the proposed model. The results of the present study provide insight into the mechanism behind rim or liquid film fragmentation.
