Inertia-Dilatancy Interplay Governs Shear-Thickening Drop Impact
Anahita Mobaseri, Leonardo Gordillo, Charles Burton +5
Combining high-speed photography with direct force measurements, we investigate the impact dynamics of drops of cornstarch-water mixtures -- a premier example of shear-thickening f…
Fluid Motion Makes the Bottle-Flip Challenge Mechanically Unintuitive But Viable
Patricio Morales, Victor Ahumada, Leonardo Gordillo +1
The bottle-flip challenge -- the upright landing of a partially filled bottle after tossing and flipping it in the air -- unexpectedly became a viral mechanics exercise. Through hi…
A synchrotron-like pumped ring resonator for water waves
Isis Vivanco, Alexander Egli, Bruce Cartwright +2
The wave-like behaviour of matter in quantum physics has spurred insightful analogies between the dynamics of particles and waves in classical systems. In this study, drawing inspi…
Fluid motion for reducing the bounce of partially filled containers
Klebbert Andrade, Javiera Catalán, Juan F. Marín +4
Certain spatial distributions of water inside partially filled containers can significantly reduce the bounce of the container. In experiments with containers filled to a volume fr…
Pedal underwater motion triggers highly-peaked resonance on water waves
Juan F. Marín, Alexander Egli, Isis Vivanco +2
Pedal wavemakers that generate surface gravity waves through bed orbital motion have been shown to produce particle-excursion patterns that mimic deep-water wave behaviour but in f…
Stress distribution and surface shock wave of drop impact
Ting-Pi Sun, Franco Alvarez-Novoa, Klebbert Andrade +3
Drop impact causes severe surface erosion, dictating many important natural, environmental and engineering processes and calling for substantial prevention and preservation efforts…
Generation of gravity waves by pedal-wavemakers
Isis Vivanco, Bruce Cartwright, A. Ledesma Araujo +2
Experimental wave generation in channels is usually achieved through wavemakers (moving paddles) acting on the surface of the water. Although practical for engineering purposes, wa…
Shape of a recoiling liquid filament
Francesco Paolo Contò, Juan F. Marín, Arnaud Antkowiak +2
We study the capillary retraction of a Newtonian semi-infinite liquid filament through analytical methods. We derive a long-time asymptotic-state expansion for the filament profile…
Dynamics of drop impact on solid surfaces: evolution of impact force and self-similar spreading
Leonardo Gordillo, Ting-Pi Sun, Xiang Cheng
We investigate the dynamics of drop impacts on dry solid surfaces. By synchronising high-speed photography with fast force sensing, we simultaneously measure the temporal evolution…
Streaming patterns in Faraday waves
Nicolas Périnet, Pablo Gutiérrez, Héctor Urra +2
Waves patterns in the Faraday instability have been studied for decades. Besides the rich dynamics that can be observed on the waves at the interface, Faraday waves hide beneath th…
Generation of surface waves by an underwater moving bottom: Experiments and application to tsunami modelling
Timothée Jamin, Leonardo Gordillo, Gerardo Ruiz-Chavarría +2
We report laboratory experiments on surface waves generated in a uniform fluid layer whose bottom undergoes a sudden upward motion. Simultaneous measurements of the free-surface de…
Measurement of velocity field in parametrically excited solitary waves
Leonardo Gordillo, Nicolás Mujica
Parametrically excited solitary waves emerge as localized structures in high-aspect-ratio free surfaces subject to vertical vibrations. Herein, we provide the first experimental ch…
