Nonlinear evolution of the centrifugal instability using a semi-linear model
Eunok Yim, Paul Billant, Francois Gallaire
We study the nonlinear evolution of the centrifugal instability developing on a columnar anticyclone with a Gaussian angular velocity using a semi-linear approach. The model consis…
Frequency selection in a gravitationally stretched capillary jet in the jetting regime
Isha Shukla, François Gallaire
A capillary jet falling under the effect of gravity continuously stretches while thinning downstream. We report here the effect of external periodic forcing on such a spatially var…
Optimal spanwise-periodic control for recirculation length in a backward-facing step flow
E. Yim, I. Shukla, F. Gallaire +1
Three-dimensional control is considered in the flow past a backward-facing step (BFS). The BFS flow at Reynolds number (defined with the step height and the maximum inlet…
Film thickness distribution in gravity-driven pancake-shaped droplets rising in a Hele-Shaw cell
Isha Shukla, Nicolas Kofman, Gioele Balestra +2
We study here experimentally, numerically and using a lubrication approach; the shape, velocity and lubrication film thickness distribution of a droplet rising in a vertical Hele-S…
Bifurcation dynamics of a particle-encapsulating droplet in shear flow
Lailai Zhu, François Gallaire
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 un…
Unraveling radial dependency effects in fiber thermal drawing
Alexis G. Page, Mathias Bechert, François Gallaire +1
Fiber-based devices with advanced functionalities are emerging as promising solutions for various applications in flexible electronics and bioengineering. Multimaterial thermal dra…
Controlling transport dynamics of confined asymmetric fibers
M. Bechert, J. Cappello, M. Daïeff +3
Transport properties of particles in confining geometries show very specific characteristics as lateral drift, oscillatory movement between lateral walls or the deformation of flex…
