Nanosplash

Abstract

Splashes are commonly seen when a solid object collides with liquid surface. It was recently found with macro-scale experiments that the surface wettability affects largely the splashing behavior; when its surface is water-repellent, the dropping object penetrates water with creating large air column (cavity) and generates large splashes. We examine similar situations with molecular dynamics simulation technique in order to compare the splashing behavior on nano scales with that on macro scales.
