Rolling Splash

A new configuration of drop splashing on a thin liquid film is investigated numericallyconsidering the rotational effect of the drop before its impact. In addition to the well-known outcomes in classic drop splash configurations(impact, liquid crown, liquid rim, etc.), unexpected phenomena can also occur, such as curved liquid bridgeformation, traveling crispswave, and colliding jetsinducing unsteady fluid chain. This numerical study requires a fully three-dimensional direct numerical simulation without any symmetry assumptions. We employ a high-fidelity hybrid front-tracking/level-set method over a wide range of non-dimensional numbers, including Reynolds, Weber, and rotation ratio numbers.
