Bubble breakup probability in turbulent flows
Aliénor Rivière, Stéphane Perrard
Bubbles drive gas and chemical transfers in various industrial and geophysical contexts, in which flows are typically turbulent. As gas and chemical transfers are bubble size depen…

Bubble shape oscillations in a turbulent environment
Aliénor Rivière, Kamel Abahri, Stéphane Perrard
We investigate bubble deformations in an homogeneous and isotropic turbulent flow by means of direct numerical simulations of a single bubble in turbulence. We examine interface de…
