Cavity deformation and bubble entrapment during the impact of droplets on a liquid pool [PDF]

Phys. Rev. E 106, 055108 (2022), 2022
The impact of droplets on a liquid pool is ubiquitous in nature and important in many industrial applications. A droplet impacting on a liquid pool can result in the pinch-off of a regular bubble or entrap a large bubble under certain impact conditions.
