Numerical simulation of immiscible incompressible viscous, viscoelastic and elastic multiphase flows

A unified numerical framework is presented for the modelling of multiphasic viscoelasticand elastic flows. The rheologies considered range from incompressible Newtonian orOldroyd-B viscoelastic fluids to Neo-Hookean elastic solids. The model is formulatedi ...

Dissipative magnetic structures and scales in small-scale dynamos

Small-scale dynamos play important roles in modern astrophysics, especially on galactic and extragalactic scales. Owing to dynamo action, purely hydrodynamic Kolmogorov turbulence hardly exists and is often replaced by hydromagnetic turbulence. Understandi ...

Weakening effect of various pore fluids on the tensile strength of granite

Guanyi Lu

Laboratory three-point bending experiments are carried out to evaluate the effect of various fluids on the tensile strength of granite. The granite specimens were tested under both dry and saturated conditions. The fluids used to saturate the granite inclu ...

Quantifying the transition of impact mechanisms of geophysical flows against flexible barrier

Xingyue Li

Flexible barriers have been increasingly used worldwide for mitigating natural hazards involving various geophysical flows. The analysis and design of flexible barriers need to distinguish two major impact mechanisms, runup and pile-up, which remain poorly ...

A Collegial Rivalry? Borelli and Viviani’s Relationship between the Divinazione and the Cimento

Simon François Dumas Primbault

When Giovanni Borelli met Galileo Galilei in Florence in 1640, he may also have crossed path with the young Vincenzio Viviani (1622–1703), last disciple of the great astronomer. He could not know, though, that he would later have a rather turbulent relatio ...

Effect of Fluid Viscosity on Earthquake Nucleation

Marie Estelle Solange Violay, Chiara Cornelio

Injection of fluids in geo-reservoirs can reduce the effective stresses at depth, lubricating the nearby faults, promoting slip and, potentially, earthquakes. High-viscous fluids are often used during hydraulic fracturing and production phases in geo-reser ...

Mechanical behaviour of fluid-lubricated faults

Marie Estelle Solange Violay, Chiara Cornelio

Fluids are pervasive in fault zones cutting the Earth's crust; however, the effect of fluid viscosity on fault mechanics is mainly conjectured by theoretical models. We present friction experiments performed on both dry and fluid-permeated silicate and car ...

Effect of fluid viscosity on fault reactivation and co‐seismic weakening

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Chiara Cornelio

High‐viscosity fluids are often used during hydraulic fracking operations in geo‐reservoirs. Here, we performed dedicated experiments to study the influence of fluid viscosity on fault reactivation and associated induced earthquakes. Experiments were condu ...

Propagation of a Radial Fluid-driven Fracture in Nonlinear Solid --around the tip of a fluid-driven fracture: process zone vs deviated fluid flow

Brice Tanguy Alphonse Lecampion, Dong Liu

Deviations from conventional hydraulic fracturing simulators’ predictions are sometimes observed in the field and laboratory. This questions the basic assumptions adopted in linear hydraulic fracture mechanics (LHFM): a linear elastic solid and a simplifie ...

Sloshing in a Hele-Shaw cell: experiments and theory

François Gallaire, Benjamin Jérémy Dollet, Francesco Viola

The response of the free liquid surface in a Hele-Shaw cell subjected to a horizontal oscillation is investigated. We study the low-oscillation-amplitude regime and we show, by varying the fluid viscosity, nu, and the forcing frequency, omega, that the rat ...
