Regimes and Breakup Model of Head-On Collisions of Unequal-Sized Water Nanodroplets

The difference in diameters of unequal-sized water nanodroplets can significantly alter the collision regimes, and a quantitative model for predicting nanodroplet breakup remains unclear. This study employs molecular dynamics simulations to investigate the head-on collisions of unequal-sized nanodro...
