Drop Impact on a Solid Surface: Supplemental Video 5
Abstract
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: Time-resolved interference imaging of the dimple formation and entrapment of an air disc under a water drop impacting a glass plate, at high impact velocity. The compression of the air inside the disc is evident from the rapid expansion following the first contact. Frame rate is 5 Mfps. From Li & Thoroddsen (2015).
