Numerical Simulation of the Impact Dynamics of a Non-spherical Droplet on a Thin Liquid Film
2025
Overview
The interaction of droplets with a liquid film plays a central role in numerous scientific and engineering processes. While most existing studies have focused on spherical droplets, it is important to note that droplets can exhibit both spherical and nonspherical shapes at the moment of impact. This study numerically investigates the dynamics of nonspherical droplet impacts on a thin liquid layer, aiming to reveal the unique behaviors and phenomena arising from shape asymmetry. The results show that impact behaviors vary considerably with droplet shape (prolate, spherical, and oblate), even under identical impact conditions. Due to its flattened geometry, an oblate droplet expands more radially, making it more susceptible to splashing and secondary droplet formation. By contrast, a prolate droplet, with its elongated profile, distributes impact energy differently, suppresses lateral spreading, and exhibits greater resistance to splashing. Droplet shape also strongly influences crown geometry, particularly the upper external crown diameter. Notably, the difference in crown diameter between prolate and oblate droplets can reach 12%–15%. In addition, the complex dynamics of air entrapment and bubble bursting are examined in detail. The findings indicate that bubble bursting occurs earlier for prolate droplets than for oblate ones.
