abstract = "A numerical study of a droplet impacting upon films of varied liquid properties is conducted. The incompressible Navier-Stokes equations coupled with the Volume of Fluid method (VOF) are solved employing the axisymmetric formulation. Discrete Phase Model (DPM) method is used to visualize the droplet impact process. The effects of viscosity and surface tension are investigated by performing the energy analysis. The crown height increases while the crown thickness reduces with decrease in liquid viscosity and surface tension. The formation of prompt splashing is also promoted as the viscosity and the surface tension decrease. It is found that the Weber number We plays a more significant role in droplet impact phenomenon compared to the influence of Reynolds number. The impact process accelerates and the splashing droplet numbers increase significantly with increase in Weber number. Through the energy analysis, it is found that the kinetic energy is not zero when the cavity diameter reaches a maximum value. The minimum of kinetic energy and maximum of total potential energy exhibit a linear relationship with 1/We. A linear relationship between We1/2and the dimensionless time to reach minimum kinetic energy is also shown.",
