Splashing and break-up of high-speed drops on wetted surfaces The splashing during the high-speed impact of drops on wetted surfaces is a complex phenomenon that ejects an irregular, undulated, and bent liquid sheet. This

From smooth liquid sheets to chaotic crowns, increasing impact speed transforms droplet splashing. This work links that transition to #ReynoldsNumber and uncovers how instabilities shape droplet size and velocity.

Dynamics of double-droplet centered impacting a hydrophobic surface featuring a micro-ridge Upon impact, the droplets undergo spreading and receding phases, with the total duration of these processes defined as the contact time. In this study, the latt

Simulations show two droplets hitting a micro‑structured hydrophobic surface bounce differently depending on spacing and angle. This dynamic is useful for surface engineering.
