The impact of an oil droplet on an air–water interface is explored for low to moderate impact
velocities. A computational fluid dynamic framework has been employed with appropriate
boundary conditions to uncover the finer features of post-impact dynamics of such ternary
systems. Simulations reveal that the impacting oil droplet opens up a “crater” on the water
surface, which initially expands and then collapses during the evolution. Simultaneously, the
oil droplet flattens, spreads, stretches, immerses, or dewets on the crater surface to manifest …
