Buoyancy driven motion of non-coalescing inertial drops: microstructure modeling with nearest particle statistics
Nicolas Fintzi, Jean-Lou Pierson, Stéphane Popinet
In this study, we analyze the various arrangements that droplets can form within dispersed buoyant emulsions, which we refer to as the study of microstructure. To this end, we have…

Turbulent properties of stationary flows in porous media
Florencia Falkinhoff, Alexandre Ponomarenko, Jean-Lou Pierson +3
In this study, we investigated the flow dynamics in a fixed bed of hydrogel beads using Particle Tracking Velocimetry to compute the velocity field in the middle of the bed for mod…

Inertial settling of an arbitrarily oriented cylinder in a quiescent flow : from short-time to quasi-steady motion
Jean-Lou Pierson
In this article, we investigate the inertial settling of an arbitrarily oriented cylinder settling under gravity. We focus on two regimes: the very short-time and long-time dynamic…
