Impact of drops on walls and films

C. Tropea, M. Marengo

Research output: Contribution to journalArticle


This review deals with the impact of drops on solid surfaces and on liquid films. The post-impingement behaviour on solid surfaces is strongly affected by the liquid-solid contact angle. When droplets impinge on liquid films, the mode of splashing is changed. The evidence relating to drop impaction is surveyed and it is concluded that there is a general lack of experimental data though there has been a rapid development of prediction tools.
