抄録

Picoliter-sized water droplets are generated for liquid metering system of μTAS using liquid-liquid interface. The dynamics of interfacial wave between two immiscible liquids has an important roll in this system, e.g., controlling droplets size. In this paper, the fluid dynamical study based on the interfacial instability theory is carried out. Comparing experimental and theoretical results, the validity of theoretical approach is discussed in detail.
