The dynamics of neutrally buoyant particles in isotropic turbulence : an experimental study

Mercredi 20 juin à 10h30

Salle Castex RDC

Résumé :

The dynamics of neutrally-buoyant particles suspended in a nearly isotropic turbulent flow is in-
vestigated experimentally, with particles of diameter larger than the Kolmogorov scale. Simultaneous measurements of particle and surrounding fluid velocities show that although the global velocity statistics of the two phases have comparable values, the particles may have different local velocity from the velocity of the neighboring fluid.
