Experimental Study on Droplet Fragmentation and Dispersion Under Heterogeneous Alternating Electric Field
In this study,the complex electrohydrodynamic behaviors of droplets in immiscible dielectric liquids under non-uniform alternating electric fields was studied based on experimental research using high-speed microscopy and PIV techniques.The microscopic morphological features and flow characteristics of charged droplets under different electric field conditions were captured accurately,and the special fragmentation patterns of charged droplets were obtained.The formation pathways of microscale droplets during the droplet fragmentation process are discovered,and two types of droplet fragmentation modes are summarized:lotus-shaped and crown-shaped.The impact of electrical parameters on the dispersion process of immiscible liquid-liquid multiphase systems was analyzed.
