A mixed flow of two immiscible liquids may form drops of one liquid in the other.Deformation and breakup of drops occur when there is sufficient hydrodynamic or surface forces from the ambient liquid;such deformation and breakup of drops is a common phenomenon in various engineering applications,such as oil-water flow in the petroleum recovery industry [1,2],stirred dispersions in the chemical industry [3,4],and melted metal and cooling liquid interactions in the nuclear industry [5,6].A typical simplified model for the mechanism study is the behaviours of a single drop against its surrounding liquid.
