Details:When a drop of liquid plummets onto a surface, the result is a splash — but not it seems if the process occurs at reduced atmospheric pressure. That fell as a bomb to the fluids community back in 2005 [Xu, Zhang, and Nagel, PRL (2005)] and it took a few years until more experiments confirmed their results and a recent paper from 2014 [Riboux & Gordillo, PRL (2014)] finally gave the theoretical background behind the mechanisms of splashing. But the surprises about drop splashes are not yet over. In 2015 Liaua et al. [Liua, Tan and Xua, PNAS (2015)] proposed an alternative mechanism for splash involving Kevin-Helmholtz instabilities (the ones that you would typically observe, for example, in the atmosphere) under the impacting droplet. Controversy mode is on. | ||
