In the present mini‐review, droplet impacting on a liquid pool, jet impingement, and binary
droplet collision of nonreacting liquids are first summarized in terms of basic phenomena …

We present a theory on the coalescence of 2 spherical liquid droplets that are initially
stationary. The evolution of the radius of a liquid neck formed upon coalescence was …

We study the effect of surfactants on the dynamics of a drop-interface coalescence using full
three-dimensional direct numerical simulations. We employ a hybrid interface-tracking/level …

The off-center collision of binary bouncing droplets of equal size was studied numerically by
a volume-of-fluid method with two marker functions, which has been justified and validated …

Binary droplet collision is a basic fluid phenomenon for many spray processes in nature and
industry involving lots of discrete droplets. It exists an inherent mirror symmetry between two …

The internal dynamics during the coalescence of a sessile droplet and a subsequently
deposited impacting droplet, with either identical or distinct surface tension, is studied …

The mixing of binary droplets is of paramount importance in microfluidic systems. In order to
reveal the mixing mechanism of two free droplets suspended in the immiscible phase, we …

In this paper, vortex-dynamical perspectives were adopted to interpret the recently reported
observation that the total viscous dissipation of off-center droplet bouncing varies …

Recent studies have demonstrated the significance of droplet spinning motion on droplet
collision outcomes and raised the question of generating spinning droplets in an …

This paper reports an experimental investigation for the impact of the head drop size as well
as the outer phase viscosity on the coalescence time of two water drops vertically aligned in …
