Sound emission from oscillating bubbles trapped by the collapse of drop-impact craters
Zi Qiang Yang, Yuan Si Tian, Er Qiang Li +1
When a drop impacts a deep pool, it forms a crater which subsequently rebounds. Under certain conditions, a dimple forms at the crater bottom, which pinches off to entrap a small b…

Dynamic transition approaching jetting singularity during the collapse of drop-impact craters
Zi Qiang Yang, Yuan Si Tian, Sigurður T Thoroddsen
Understanding the dynamical transition from capillary-driven to pure inertial focusing is important to revealing the mechanism underlying the most singular micro-jetting produced f…
