Description

ÉTUDIANT 2: Vincent Volle
A liquid jet or stream of droplets impacting a liquid surface and thereby, entraining the surrounding gas to form a bubble cloud is among the most-common daily-life phenomena. Understanding and modeling such bubble clouds is crucial for multi-phase mixing processes in nature and in industrial techniques for pollution control, turbine operation and performance, oxygenation of water resources, among others. From a more fundamental point of view, the physics of such “bubbly” flows is at the margin of classical fluid dynamics. Based on recent studies in our group which provide a strong theoretical basis and large amount of experimental data, there is wide scope to further improve our understanding via direct numerical simulations of such two-phase flows. In this context, the internship aims to characterize the bubble cloud formed by circular jets, and droplet trains, using numerical simulations (Basilisk Flow Solver).
