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 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…
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…
Phase transition to turbulence via moving fronts
Sébastien Gomé, Aliénor Rivière, Laurette S. Tuckerman +1
Directed percolation (DP), a universality class of continuous phase transitions, has recently been established as a possible route to turbulence in subcritical wall-bounded flows.…
Experimental observations and modeling of sub-Hinze bubble production by turbulent bubble break-up
Daniel J. Ruth, Aditya K. Aiyer, Aliénor Rivière +2
We present experiments on large air cavities spanning a wide range of sizes relative to the Hinze scale , the scale at which turbulent stresses are balanced by surfac…
Capillary driven fragmentation of large gas bubbles in turbulence
A. Rivière, D. Ruth, W. Mostert +2
The bubble size distribution below a breaking wave is of paramount interest when quantifying mass exchanges between the atmosphere and oceans. Mass fluxes at the interface are driv…
Bubble deformation by a turbulent flow
Stéphane Perrard, Aliénor Rivière, Wouter Mostert +1
We investigate the modes of deformation of an initially spherical bubble immersed in a homogeneous and isotropic turbulent background flow. We perform direct numerical simulations…
