Many authors defined different outcomes regarding this phenomenon. Rioboo et al. [1] revealed more than six possible outcomes, which include deposition, stick, crown splash, prompt splash, among others. These different outcomes may vary depending on many factors such as the liquid drop parameters (diameter, impact velocity, viscosity, surface tension, etc.), the liquid film parameters (thickness, characteristics of the underlying surface, etc.) and the surrounding gas (velocity, pressure, etc.).engLiquid filmsDroplet impingingJet A-1BiofuelVolume of Fluidjournal article10.1615/TFEC2019.mph.028384
