Turbulence induced by a swarm of rising bubbles from coarse-grained simulations
Rémi Zamansky, Florian Le Roy de Bonneville, Frederic Risso
We performed numerical simulations of a homogeneous swarm of bubbles rising at large Reynolds number, Re = 760 with volume fractions ranging from 1% to 10%. We consider a simplifie…

Revisiting the framework for intermittency in Lagrangian stochastic models for turbulent flows: a way to an original and versatile numerical approach
Roxane Letournel, Ludovic Goudenège, Rémi Zamansky +2
The characterization of intermittency in turbulence has its roots in the K62 theory, and if no proper definition is to be found in the literature, statistical properties of intermi…
