Popis:	97 This study investigates the temporal characteristics of an impinging droplet onto liquid film of different thickness and various properties via a high speed camera. The depth, the diameter, the receding velocity of the cavity structure and the form of the central jet above the liquid film are the subjects of primary interest. Four liquid film thickness, six different properties are employed to realize the transient behavior of the impinging droplet onto these liquid films. The experimental results show that: (a) During the impacting stage (t * 8): the differences between the viscosity and the film thickness of the liquid film will not strongly affect the of withdrawing trend. However, if the viscosity of the liquid film increases, the penetration depth the cavity structure will decrease.
