“…and exhibit a height-varying modulation, especially from low to moderate concentrations Φ 0 . The development of these non-homogeneous concentration profiles might be due to multiple factors, such as droplet migration induced by a non-uniform shear field [80][81][82] (owing to the large scale circulation of convection) or droplet depletion due to interactions with the walls. A precise description disentangling these various mechanisms and discriminating which one contributes most, lies beyond the scope of the present work.…”

“…We observe, indeed, they are not constant and exhibit a height-varying modulation, especially from low to moderate concentrations Φ 0 . The development of these non-homogeneous concentration profiles might be due to multiple factors, such as droplet migration induced by a non-uniform shear field [91][92][93] (owing to the large scale circulation of convection) or droplet depletion due to interactions with the walls.

“…2010). Particle-scale deformation associated with stronger flows is an example of a perturbative mechanism, affecting hydrodynamic interactions at separations, and breaking the symmetry of more distant, non-contacting pair trajectories (Lopez & Graham 2007; Lac & Barthès-Biesel 2008; Singh & Sarkar 2015; Malipeddi & Sarkar 2019 a , b ).…”
