Sub-Kolmogorov Intermittency and Multifractal Dissipation in Multiphase Turbulence
Marco Crialesi-Esposito, Alienor Riviere, Sergio Chibbaro
Multiphase turbulence displays stronger intermittency than its single-phase counterpart, yet the origin and geometrical organization of its most intense small-scale fluctuations re…
Deformation and stability of a gas bubble in a biaxial straining flow
Aliénor Rivière, David Fabre, Jacques Magnaudet +1
Taking advantage of the recently developed L-ALE framework [Sierra-Ausin \textit{et al.}, Phys. Rev. Fluids {\bf{7}}, 113603 (2022)], we characterize the linear dynamics of an inco…
Breakup cascade in gas filament
Aliénor Rivière, Zehua Liu, Jishen Zhang +3
Despite its importance in both geophysical and industrial contexts, the inertial fragmentation of gas filaments has received much less attention than their liquid counterparts. Yet…
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…
