PIV Measurement of a Droplet Impact on a Thin Fluid Layer
Upon the impact of a droplet onto a thin fluid layer, the fluid is pushed away around the impact point until it reaches a certain radius to go upward to form a thin liquid wall. At the tip of the liquid wall, the circumferential instability creates a several droplets, which is commonly known as milk crown. The size and the height of the crown and the number of the tip droplets are affected by the conditions of a droplet and of a fluid layer. Presently, the fundamental characteristics of the milk crown have been extensively investigated based on the flow visualization by the high-speed camera. Moreover, the motions of the fluid layer and the liquid film have been measured with the aid of PIV. The result reveals several interesting features of the formation of a milk crown.
