Study of Pinch-Off of Liquid-Liquid Flow in Micro- and Macrogravity Conditions

The pinch-off of immiscible fluids in a liquid-liquid flow is studied under micro- and macro-gravity conditions, and new methods of producing a constant droplet size are explored. The controlling variables are velocity of the flow, frequency and amplitude of the forcing signal. Surface tension reducing agents (surfactants) are introduced into the system and their affect on the pinch-off is recorded.
