Active bacterial pattern formation in evaporating droplets
Twan J. S. Wilting, Adriana W. B. P. Reijnier, Michiel H. M. Brebels +3
Bacteria living on surfaces are often confined to droplets. When these droplets evaporate, the motion of the liquid-air interface and the associated internal capillary flow confine…
Evaporation-driven liquid flow in sessile droplets
Hanneke Gelderblom, Christian Diddens, Alvaro Marin
The evaporation of a sessile droplet spontaneously induces an internal capillary liquid flow. The surface-tension driven minimisation of surface area and/or surface-tension differe…
Drop fragmentation by laser-pulse impact
Alexander L. Klein, Dmitry Kurilovich, Henri Lhuissier +4
We study the fragmentation of a liquid drop that is hit by a laser pulse. The drop expands into a thin sheet that breaks by the radial expulsion of ligaments from its rim and the n…
Solidification of liquid metal drops during impact
Marise V. Gielen, Riëlle de Ruiter, Robin B. J. Koldeweij +3
Hot liquid metal drops impacting onto a cold substrate solidify during their subsequent spreading. Here we experimentally study the influence of solidification on the outcome of an…
Oblique droplet impact onto a deep liquid pool
Sten A. Reijers, Bo Liu, Detlef Lohse +1
The oblique impact of a liquid droplet onto a deep liquid pool is studied numerically with the adaptive volume-of-fluid solver Basilisk. The splashing threshold, cavity formation,…
Expansion Dynamics After Laser-Induced Cavitation in Liquid Tin Microdroplets
Dmitry Kurilovich, Tiago de Faria Pinto, Francesco Torretti +9
The cavitation-driven expansion dynamics of liquid tin microdroplets is investigated, set in motion by the ablative impact of a 15-ps laser pulse. We combine high-resolution strobo…
Supressed splashing on elastic membranes
Marise V. Gielen, Riëlle de Ruiter, Jacco H. Snoeijer +1
The dynamics of drop impact on solid surfaces can be changed significantly by tuning the elasticity of the solid. Most prominently, the substrate deformation causes an increase in…
Droplet deformation by short laser-induced pressure pulses
Sten A. Reijers, Jacco H. Snoeijer, Hanneke Gelderblom
When a free-falling liquid droplet is hit by a laser it experiences a strong ablation driven pressure pulse. Here we study the resulting droplet deformation in the regime where the…
Oblique drop impact onto a deep liquid pool
Marise V. Gielen, Pascal Sleutel, Jos Benschop +7
Oblique impact of drops onto a solid or liquid surface is frequently observed in nature. Most studies on drop impact and splashing, however, focus on perpendicular impact. Here, we…
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…
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…
Stokes flow in a drop evaporating from a liquid subphase
Hanneke Gelderblom, Howard A. Stone, Jacco H. Snoeijer
The evaporation of a drop from a liquid subphase is investigated. The two liquids are immiscible, and the contact angles between them are given by the Neumann construction. The eva…
Oscillations of a gas pocket on a liquid-covered solid surface
Hanneke Gelderblom, Aaldert G. Zijlstra, Leen van Wijngaarden +1
The dynamic response of a gas bubble entrapped in a cavity on the surface of a submerged solid subject to an acoustic field is investigated in the linear approximation. We derive s…
Stokes flow near the contact line of an evaporating drop
Hanneke Gelderblom, Oscar Bloemen, Jacco H. Snoeijer
The evaporation of sessile drops in quiescent air is usually governed by vapour diffusion. For contact angles below , the evaporative flux from the droplet tends to diver…
Order-to-disorder transition in ring-shaped colloidal stains
Álvaro G. Marín, Hanneke Gelderblom, Detlef Lohse +1
A colloidal dispersion droplet evaporating from a surface, such as a drying coffee drop, leaves a distinct ring-shaped stain. Although this mechanism is frequently used for particl…
Avalanche of particles in evaporating coffee drops
Alvaro G. Marin, Hanneke Gelderblom, Jacco Snoeijer +1
The pioneering work of Deegan et al. [Nature 389, (1997)] showed how a drying sessile droplet suspension of particles presents a maximum evaporating flux at its contact line which…
How water droplets evaporate on a superhydrophobic substrate
Hanneke Gelderblom, Alvaro G. Marin, Hrudya Nair +4
Evaporation of water droplets on a superhydrophobic substrate, on which the contact line is pinned, is investigated. While previous studies mainly focused on droplets with contact…
