Laser impact on a drop
Alexander L. Klein, Claas Willem Visser, Wilco Bouwhuis +6
The impact of a laser pulse on a highly absorbing liquid drop can lead to a violent response: the drop is accelerated, strongly deforms, and eventually fragments. Shock waves, the…
Drop deformation by laser-pulse impact
Hanneke Gelderblom, Henri Lhuissier, Alexander L. Klein +4
A free-falling absorbing liquid drop hit by a nanosecond laser-pulse experiences a strong recoil-pressure kick. As a consequence, the drop propels forward and deforms into a thin s…
The effect of surface wettability on inertial pouring flows
Wilco Bouwhuis, Jacco H. Snoeijer
A liquid poured from a curved solid surface can separate as a steady jet or sheet, or trickle down along the solid surface. It was shown by Duez et al. [Phys. Rev. Lett. 104, 08450…
Universal mechanism for air entrainment during liquid impact
Maurice H. W. Hendrix, Wilco Bouwhuis, Devaraj van der Meer +2
When a mm-sized liquid drop approaches a deep liquid pool, both the interface of the drop and the pool deform before the drop touches the pool. The build up of air pressure prior t…
Drop Shaping by Laser-Pulse Impact
Alexander L. Klein, Wilco Bouwhuis, Claas Willem Visser +6
We show how the deposition of laser energy induces propulsion and strong deformation of an absorbing liquid body. Combining high speed with stroboscopic imaging, we observe that a…
Initial surface deformations during impact on a liquid pool
Wilco Bouwhuis, Maurice H. W. Hendrix, Devaraj van der Meer +1
A tiny air bubble can be entrapped at the bottom of a solid sphere that impacts onto a liquid pool. The bubble forms due to the deformation of the liquid surface by a local pressur…
Oscillating and star-shaped drops levitated by an airflow
Wilco Bouwhuis, Koen G. Winkels, Ivo R. Peters +3
We investigate the spontaneous oscillations of drops levitated above an air cushion, eventually inducing a breaking of axisymmetry and the appearance of `star drops'. This is stron…
Maximal air bubble entrainment at liquid drop impact
Wilco Bouwhuis, Roeland C. A. van der Veen, Tuan Tran +7
At impact of a liquid drop on a solid surface an air bubble can be entrapped. Here we show that two competing effects minimize the (relative) size of this entrained air bubble: For…
