Fault reactivation during fluid pressure oscillations: transition from stable to unstable slip

Marie Estelle Solange Violay, François Xavier Thibault Passelègue, Carolina Giorgetti, Corentin Jean-Marie Rémi Noël

High‐pressure fluid injection in deep geo‐reservoirs can induce earthquakes. Recent observations suggest that cyclic injections might trigger less seismicity than monotonic injections. Here, we report triaxial laboratory experiments conducted on faulted qu ...

Computing heteroclinic orbits using adjoint-based methods

Tobias Schneider, Mirko Farano

Transitional turbulence in shear flows is supported by a network of unstable exact invariant solutions of the Navier-Stokes equations. The network is interconnected by heteroclinic connections along which the turbulent trajectories evolve between invariant ...

Absolute/convective secondary instabilities and the role of confinement in free shear layers

François Gallaire, Cristobal Manuel Arratia Martinez, Saviz Mowlavi

We study the linear spatiotemporal stability of an infinite row of equal point vortices under symmetric confinement between parallel walls. These rows of vortices serve to model the secondary instability leading to the merging of consecutive (Kelvin-Helmho ...

A semi-infinite hydraulic fracture driven by a shear-thinning fluid

Brice Tanguy Alphonse Lecampion, Fatima-Ezzahra Moukhtari

We use the Carreau rheological model which properly accounts for the shear-thinning behaviour between the low and high shear rate Newtonian limits to investigate the problem of a semi-infinite hydraulic fracture propagating at a constant velocity in an imp ...

Fluid dynamics of flow fields in a disposable 600-mL orbitally shaken bioreactor

Florian Maria Wurm, David Hacker, Dominique Terry Monteil Jr, Likuan Zhu

Orbitally shaken bioreactors (OSRs) are commonly used for the cultivation of mammalian cells in suspension. Here we conducted a three-dimensional computational fluid dynamics (CFD) simulation to characterize the fluid field in the disposable 600-mL orbital ...

Internal force distribution in RC slabs subjected to punching shear

Aurelio Muttoni, Beatrice Belletti

Reinforced concrete (RC) two-way slabs without shear reinforcement are commonly used in many structural systems. This paper investigated the structural behaviour of RC slabs subjected to concentrated loads leading to punching shear failure using shell and ...

Bifurcation Dynamics of a Particle-Encapsulating Droplet in Shear Flow

François Gallaire, Lailai Zhu

To understand the behavior of composite fluid particles such as nucleated cells and double emulsions in flow, we study a finite-size particle encapsulated in a deforming droplet under shear flow as a model system. In addition to its concentric particle-dro ...

Propagation of a height contained hydraulic fracture in turbulent flow regimes

Brice Tanguy Alphonse Lecampion, Haseeb Zia

We investigate theoretically and numerically the impact of the transition from laminar to turbulent flow on the propagation of a height contained hydraulic fracture (i.e. PKN geometry). We account for the inertial terms in the balance of momentum and expre ...
