Study on the generation process of small water droplets driven by bubbles penetrating oil-water interface
Details
Generation of tiny droplets caused by surface tension force at gas-liquid and liquid-liquid interface are captured by high speed (500 frames per second) and high resolution (a square with 1024 pixels long) video cameras. When a air bubble rise up through an oil-water interface, three types of water droplets are generated in the oil layer. The sources of the droplets are revealed by using high speed video cameras. Surface tension force plays an important role to the phenomena. It connects entrained water with a rising bubble, drives a jet flow, and cause waves on the interface.
