Abstract

The collision of liquid droplets is widely seen in nature and needs to be carefully controlled in biological and industrial processes, such as self-cleaning and anti-icing. In this work, we designed an experiment to investigate the effects of bullet droplets enfolded particles on the head-on collision of droplets on the substrate. We compared the results of collisions for the particle-free droplets and particle-involved droplets. The process of droplets collision with particles is subdivided into two stages: the collision stage, and the stretching stage. For the collision stage, the experimental process is consistent with the droplet collisions without particles, where the commonality is reflected as the elongated tail of the stationary droplet due to collision. For the stretching stage, since the particles in the bullet droplets are deposited on the substrate surface, the deposited droplets continue to pull the tail of the stationary droplet after the coalescence of droplets, causing the tail to break.
