Rare transitions between collective states in an active fluid via a weakly nonlinear reduction
Yves-Marie Ducimetière, Michael J. Shelley
We study a model for a dilute suspension of rod-like particles swimming at constant velocity in a Stokes flow. As the translational diffusivity of the particles decreases, a two-di…
Nonmodal amplitude equations
Yves-Marie Ducimetière, François Gallaire
We consider fluid flows for which the linearized Navier-Stokes operator is strongly non-normal. The responses of such flows to external perturbations are spanned by a generically v…
Noise-induced transitions past the onset of a steady symmetry-breaking bifurcation: the case of the sudden expansion
Yves-Marie Ducimetière, Edouard Boujo, François Gallaire
We consider fluid flows, governed by the Navier-Stokes equations, subject to a steady symmetry-breaking bifurcation and forced by a weak noise acting on a slow time scale. By gener…
On the liquid film instability of an internally coated horizontal tube
Shahab Eghbali, Yves-Marie Ducimetiere, Edouard Boujo +1
We study numerically and theoretically the gravity-driven flow of a viscous liquid film coating the inner side of a horizontal cylindrical tube and surrounding a shear-free dynamic…
Breaking one into three: surface-tension-driven droplet breakup in T-junctions
Jiande Zhou, Yves-Marie Ducimetière, Daniel Migliozzi +4
Droplet breakup is an important phenomenon in the field of microfluidics to generate daughter droplets. In this work, a novel breakup regime in the widely studied T-junction geomet…
Weak nonlinearity for strong nonnormality
Yves-Marie Ducimetière, Edouard Boujo, François Gallaire
We propose a theoretical approach to derive amplitude equations governing the weakly nonlinear evolution of nonnormal dynamical systems when they experience transient growth or res…
