A Surfactant Prediction Model for Rising Bubbles
Lim Chi Tung James, Ivo R. Peters, Swathi Krishna
Bubbles released from a needle show shape deformations that depend on the surfactant concentration of the surrounding liquid. We develop a model that predicts the surfactant concen…
Bubble collapse near porous plates
Elijah D. Andrews, David Fernández Rivas, Ivo R. Peters
The collapse of a gas or vapour bubble near a non-porous boundary is directed at the boundary due to the asymmetry induced by the nearby boundary. High surface pressure and shear s…
Modelling bubble collapse anisotropy in complex geometries
Elijah D. Andrews, Ivo R. Peters
A gas or vapor bubble collapsing in the vicinity of a rigid boundary displaces towards the boundary and produces a high-speed jet directed at the boundary. This behavior has been s…
Lasting effects of discontinuous shear thickening in cornstarch suspensions upon flow cessation
Jae Hyung Cho, Andrew H. Griese, Ivo R. Peters +1
Dense suspensions that exhibit discontinuous shear thickening (DST) undergo complex stress relaxation when the flow abruptly stops. Using rotational rheometry, we study the two-ste…
Collision of Dynamic Jamming Fronts in a Dense Suspension
Olav Ro mcke, Ivo R. Peters, R. Jason Hearst
Dynamic jamming is a phenomenon whereby a dense suspension switches from a fluid-like to a solid-like state when subjected to sufficient stress and deformation. Large enough system…
Characterizing the surface texture of a dense suspension undergoing dynamic jamming
Olav Rømcke, Ivo R. Peters, R. Jason Hearst
Measurements of the surface velocity and surface texture of a freely propagating shear jamming front in a dense suspension are compared. The velocity fields are captured with parti…
Cavity collapse near slot geometries
Elijah D. Andrews, David Fernández Rivas, Ivo R. Peters
The collapse of a gas or vapour bubble near a solid boundary produces a jet directed towards the boundary. High surface pressure and shear stress induced by this jet can damage, or…
Getting jammed in all directions: Dynamic shear jamming around a cylinder towed through a dense suspension
Olav Rømcke, Ivo R. Peters, R. Jason Hearst
Experimental results of towing a cylinder through a dense suspension of cornstarch and sucrose-water are presented. Focus is placed on the jamming fronts that exist in such systems…
Jet direction in bubble collapse within rectangular and triangular channels
Lebo Molefe, Ivo R. Peters
A vapor bubble collapsing near a solid boundary in a liquid produces a liquid jet that points toward the boundary. The direction of this jet has been studied for boundaries such as…
Bubble Collapse and Jet Formation in Corner Geometries
Yoshiyuki Tagawa, Ivo R. Peters
The collapse of a vapor bubble near a flat solid boundary results in the formation of a jet that is directed towards the boundary. In more complex geometries such as corners, predi…
Constitutive relations for shear fronts in shear-thickening suspensions
Endao Han, Matthieu Wyart, Ivo R. Peters +1
We study the fronts that appear when a shear-thickening suspension is submitted to a sudden driving force at a boundary. Using a quasi-one-dimensional experimental geometry, we ext…
High-speed ultrasound imaging in dense suspensions reveals impact-activated solidification due to dynamic shear jamming
Endao Han, Ivo R. Peters, Heinrich M. Jaeger
A remarkable property of dense suspensions is that they can transform from liquid-like at rest to solid-like under sudden impact. Previous work showed that this impact-induced soli…
From splashing to bouncing: the influence of viscosity on the impact of suspension droplets on a solid surface
Martin H. Klein Schaarsberg, Ivo R. Peters, Menachem Stern +3
We experimentally investigated the splashing of dense suspension droplets impacting a solid surface, extending prior work to the regime where the viscosity of the suspending liquid…
Dynamic shear jamming in dense granular suspensions under extension
Sayantan Majumdar, Ivo R. Peters, Endao Han +1
Unlike dry granular materials, a dense granular suspension like cornstarch in water can strongly resist extensional flows. At low extension rates, such a suspension behaves like a…
Volume entrained in the wake of a disc intruding into an oil-water interface
Ivo R. Peters, Matteo Madonia, Detlef Lohse +1
An object moving through a plane interface into a fluid deforms the interface in such a way that fluid from one side of the interface is entrained into the other side, a phenomenon…
Dynamic jamming of iceberg-choked fjords
Ivo R. Peters, Jason M. Amundson, Ryan Cassotto +4
We investigate the dynamics of ice mélange by analyzing rapid motion recorded by a time-lapse camera and terrestrial radar during several calving events that occurred at Jakobshavn…
Quasi-2D dynamic jamming in cornstarch suspensions: visualization and force measurements
Ivo R. Peters, Heinrich M. Jaeger
We report experiments investigating jamming fronts in a floating layer of cornstarch suspension. The suspension has a packing fraction close to jamming, which dynamically turns int…
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…
Splashing onset in dense suspension droplets
Ivo R. Peters, Qin Xu, Heinrich M. Jaeger
We investigate the impact of droplets of dense suspensions onto a solid substrate. We show that a global hydrodynamic balance is unable to predict the splash onset and propose to r…
Air flow in a collapsing cavity
Ivo R. Peters, Stephan Gekle, Detlef Lohse +1
We experimentally study the airflow in a collapsing cavity created by the impact of a circular disk on a water surface. We measure the air velocity in the collapsing neck in two wa…
Splash wave and crown breakup after disc impact on a liquid surface
Ivo R. Peters, Devaraj van der Meer, J. M. Gordillo
In this paper we analyze the impact of a circular disc on a free surface using experiments, potential flow numerical simulations and theory. We focus our attention both on the stud…
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…
Highly focused supersonic microjets: numerical simulations
Ivo R. Peters, Yoshiyuki Tagawa, Nikolai Oudalov +4
By focusing a laser pulse inside a capillary partially filled with liquid, a vapour bubble is created which emits a pressure wave. This pressure wave travels through the liquid and…
Highly focused supersonic microjets
Yoshiyuki Tagawa, Nikolai Oudalov, Claas Willem Visser +5
The paper describes the production of thin, focused microjets with velocities up to 850 m/s by the rapid vaporization of a small mass of liquid in an open liquid-filled capillary.…
