Drop Impact on a Solid Surface: Supplemental Video 11

A supplemental video from the 2016 review by C. Josserand and S.T. Thoroddsen, "Drop Impact on a Solid Surface," from the Annual Review of Fluid Mechanics.

Shown: The impact of a compound drop, outer drop is a water/glycerin mixture of viscosity 2 cP. It contains 20 inner perfluorohexane droplets, which are more dense and migrate toward the bottom free surface of the large drop. For impact velocity V ≃ 4 m/s, drop D ≃ 4 mm. Frame rate is 12 kfps.
