Dynamics of droplet adsorption at the liquid-liquid interface of parallel flow in a microchannel

The dynamics of droplet adsorption at the liquid-liquid interface of parallel flow in a microchannel is investigated. The adsorption process is divided into three distinct stages: the liquid bridge expansion stage, the rapid deformation stage and the spreading stage. The dynamic behavior of droplet adsorption is elucidated by quantitatively analyzing the evolution of adsorption length and droplet height over time under different droplet viscosities. This experiment makes a positive contribution to further reveal the droplet adsorption mechanism and expand the application prospect of microfluidic technology.
