Abstract

Due to the nonlinear dynamic characteristics

the liquid-liquid interface rupture process is often accompanied by the generation of satellite droplets

which poses a challenge to the uniformity and precision of droplets-based microfluidic technology. The complex dynamic characteristics of interfacial instability of microfluidics are explained

and the factors influencing the interfacial instability are analyzed. In addition

the phenomenon and mechanism of satellite droplet formation associated with the interfacial instability are revealed. Based on the new concept of the inertial microfluidics

the mechanism of the separation of satellite droplet by using the inertial microfluidics is highlighted. The integration principle of generation-inertial microfluidics separation for the satellite droplet is proposed

as well as the parallelization criterion for the corresponding numbering-up. The implementation of this topic is beneficial for the realization of the target of precision in producing monodisperse droplets with microfluidics technology

laying a solid foundation for the interfacial dynamics and manipulation of microfluidics and complex fluids.
