Viscoelasticity reduces the droplet size in mucosalivary film fragmentation during intense respiratory events
Mogeng Li, Youssef Saade, Stéphane Zaleski +3
We examine the fundamental fluid dynamical mechanisms dictating the generation of bioaerosols in the human trachea during intense respiratory events such as coughing and sneezing,…
Deforming ice with drops
Duco van Buuren, Pallav Kant, Jochem G. Meijer +2
A uniform solidification front undergoes non-trivial deformations when encountering an insoluble dispersed particle in a melt. For solid particles, the overall deformation characte…
Freezing-induced topological transition of double-emulsion
Jochem G. Meijer, Pallav Kant, Detlef Lohse
Solidification of complex liquids is pertinent to numerous natural and industrial processes. Here, we examine the freezing of a W/O/W double-emulsion, i.e., water-in-oil compound d…
Autothermotaxis of volatile drops
Pallav Kant, Mathieu Souzy, Nayoung Kim +2
When a drop of a volatile liquid is deposited on a uniformly heated wettable, thermally conducting substrate, one expects to see it spread into a thin film and evaporate. Contrary…
Thin-Film-Mediated Deformation of Droplet during Cryopreservation
Jochem G. Meijer, Pallav Kant, Duco Van Buuren +1
Freezing of dispersions is omnipresent in science and technology. While the passing of a freezing front over a solid particle is reasonably understood, this is not so for soft part…
Bags mediated film atomization in a cough machine
Pallav Kant, César Pairetti, Youssef Saade +3
We combine experiments and numerical computations to examine underlying fluid mechanical processes associated with bioaerosol generation during violent respiratory manoeuvres, such…
Taylor-Culick retractions and the influence of the surroundings
Vatsal Sanjay, Uddalok Sen, Pallav Kant +1
When a freely suspended liquid film ruptures, it retracts spontaneously under the action of surface tension. If the film is surrounded by air, the retraction velocity is known to a…
Pattern formation during the impact of a partially-frozen binary droplet on a cold surface
Pallav Kant, Henrik Müller-Groeling, Detlef Lohse
Impact of a droplet on an undercooled surface is a complex phenomenon as it simultaneously instigates several physical processes that cover a broad spectrum of transport phenomena…
Initial solidification dynamics of spreading droplets
Robin B. J. Koldeweij, Pallav Kant, Kirsten Harth +5
When a droplet is brought in contact with an undercooled surface, it wets the substrate and solidifies at the same time. The interplay between the phase transition effects and the…
Fast-freezing kinetics inside a droplet impacting on a cold surface
Pallav Kant, Robin B. J. Koldeweij, Kirsten Harth +2
Freezing or solidification of impacting droplets is omnipresent in nature and technology, be it a rain droplet falling on a supercooled surface, be it in inkjet printing where ofte…
Splitting droplet through coalescence of two different three-phase contact lines
Haitao Yu, Pallav Kant, Brendan Dyett +2
Moving contact lines of more than two phases dictate a large number of interfacial phenomena. Despite its significance to fundamental and applied processes, the contact lines at a…
POLED displays: Robust printing of pixels
P. Kant, A. L. Hazel, M. Dowling +2
The fabrication of a high-quality POLED (Polymeric Organic Light Emitting Diode) display requires the deposition of identical, uniform fluid films into a large number of shallow re…
Controlling droplet spreading with topography
Pallav Kant, Andrew L. Hazel, Mark Dowling +2
We present a novel experimental system that can be used to study the dynamics of picoliter droplet spreading over substrates with topographic variations. We concentrate on spreadin…
