Revisiting the role of friction coefficients in granular collapses: confrontation of 3-D non-smooth simulations with experiments
Gauthier Paul Daniel Marie Rousseau
In this paper, transient granular flows are examined both numerically and experimentally. Simulations are performed using the continuous three-dimensional (3-D) granular model introduced in Daviet & Bertails-Descoubes (ACM Trans. Graph., vol. 35, no. 4, 20 ...
Cambridge2023Dielectric Elastomer Actuator-Based Valveless Impedance-Driven Pumping for Meso- and Macroscale Applications
Yves Perriard, Yoan René Cyrille Civet, Thomas Guillaume Martinez, Francesco Clavica, Armando Matthieu Walter, Amine Benouhiba, Silje Ekroll Jahren
Impedance pumps are simple designs that allow the generation or amplification of flow. They are fluid-filled systems based on flexible tubing connected to tubing with different impedances. A periodic off-center compression of the flexible tubing causes the ...
2023Numerical modeling of ground movement above underground salt mines in Tuzla city, Bosnia and Herzegovina
The subsidence occurring in the city of Tuzla in Bosnia and Herzegovina (B&H) is an important issue which has caused several damages in the past decades. This phenomena is related to the massive extraction of salt and the presence of salt caverns below the ...
2023A new insight into the dynamic impact between geophysical flow and rigid barrier
Understanding the interaction between complicated geophysical flows and barriers remains a critical challenge for hazards countermeasures in engineering design. In this study, the impact of geophysical flows on a rigid barrier is studied numerically using ...
ELSEVIER SCI LTD2022Scaling Description of Creep Flow in Amorphous Solids
Matthieu Wyart, Thomas Willem Jan de Geus, Wencheng Ji, Marko Popovic
Amorphous solids such as coffee foam, toothpaste, or mayonnaise display a transient creep flow when a stress E is suddenly imposed. The associated strain rate is commonly found to decay in time as gamma_ -t-nu, followed either by arrest or by a sudden flui ...
AMER PHYSICAL SOC2022A plane‐strain hydraulic fracture driven by a shear‐thinning Carreau fluid
Brice Tanguy Alphonse Lecampion, Lucas Pereira
We study the propagation of a plane‐strain hydraulic fracture driven by a shear thinning fluid following a Carreau rheology. We restrict to the impermeable medium case and quantify in details the impact on fracture growth of the shear‐thinning properties o ...
2021Experimental study of impulse waves generated by viscoplastic fluid
Landslide-generated waves, also called impulse waves, occur as a result of the intrusion of landslides (such as rock falls, debris flows, and avalanches) into bodies of water (such as lakes, reservoirs, and seas). The objective of this thesis was to study ...
EPFL2020Generalization of Fourier’s Law into Viscous Heat Equations
Nicola Marzari, Andrea Cepellotti, Michele Simoncelli
Heat conduction in dielectric crystals originates from the dynamics of atomic vibrations, whose evolution is well described by the linearized Boltzmann transport equation for the phonon populations. Recently, it was shown that thermal conductivity can be r ...
2020Mechanical behavior of fluid-induced earthquakes
Fluids play an important role in fault zone and in earthquakes generation. Fluid pressure reduces the normal effective stress, lowering the frictional strength of the fault, potentially triggering earthquake ruptures. Fluid injection induced earthquakes (F ...
2020Viscoplastic fluid impacting a body of water: predicting wave features from the fluid properties
Christophe Ancey, Zhenzhu Meng, Yating Hu
We investigate viscoplastic fluids (described using a Herschel–Bulkley model) striking a body of water: a fixed volume of a viscoplastic material (a polymeric gel called Carbopol ultrez 10) initially contained in a box is released on a slope and flows down ...
