Partial Coalescence

Written by

When a drop coalesceces into a pool, it sometimes leaves behind a smaller daughter drop. When this happens, it's known as partial coalescence.

To tune process to produce multiple droplets, the researchers added surfactant to thin the rebounding jet and prime it to break up.

With a little more surfactant and a little higher impact speed, they succeed in generating multiple drops during coalescence.
