摘要：
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. © All Right Reserved.
