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…
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…
Coherence of velocity fluctuations in turbulent flows
G. Prabhudesai, S. Perrard, F. Pétrélis +1
We investigate the spatio-temporal quantity of coherence for turbulent velocity fluctuations at spatial distances of the order or larger than the integral length scale . Usi…
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…
Turbulent windprint on a liquid surface
Stéphane Perrard, Adrián Lozano-Durán, Marc Rabaud +2
We investigate the effect of a light turbulent wind on a liquid surface, below the onset of wave generation. In that regime, the liquid surface is populated by small disorganised d…
