Higher-order meniscus oscillations driven by flow-focusing leading to bubble pinch off and entrainment in a piezo acoustic inkjet nozzle
Arjan Frates, Maaike Rump, Roger Jeurissen +8
The stability of high-end piezo-acoustic drop-on-demand (DOD) inkjet printing is sometimes compromised by the entrainment of an air bubble inside the ink channel. Here, bubble pinc…

Drop Impact on Hot Plates: Contact times, Lift-off and the Lamella Rupture
Sang-Hyeon Lee, Kirsten Harth, Maaike Rump +4
When a liquid drop impacts on a heated substrate, it can remain deposited, or violently boil in contact, or lift off with or without ever touching the surface. The latter is known…
