Large spheres motion in a non homogeneous turbulent flow
Nathanael Machicoane, Robert Zimmermann, Lionel Fiabane +3
We investigate the dynamics of very large particles freely advected in a turbulent von Karman flow. Contrary to other experiments for which the particle dynamics is generally studi…
Characterizing flows with an instrumented particle measuring Lagrangian accelerations
Robert Zimmermann, Lionel Fiabane, Yoann Gasteuil +2
We present in this article a novel Lagrangian measurement technique: an instrumented particle which continuously transmits the force/acceleration acting on it as it is advected in…
Measuring Lagrangian accelerations using an instrumented particle
Robert Zimmermann, Lionel Fiabane, Yoann Gasteuil +2
Accessing and characterizing a flow impose a number of constraints on the employed measurement techniques; in particular optical methods require transparent fluids and windows in t…
On the clustering of finite-size particles in turbulence
Lionel Fiabane, Robert Zimmermann, Romain Volk +2
We investigate experimentally the spatial distributions of heavy and neutrally buoyant particles of finite size in a fully turbulent flow. As their Stokes number (i.e. ratio of the…
Rotational intermittency and turbulence induced lift experienced by large particles in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
The motion of a large, neutrally buoyant, particle, freely advected by a turbulent flow is determined experimentally. We demonstrate that both the translational and angular acceler…
Tracking the dynamics of translation and absolute orientation of a sphere in a turbulent flow
Robert Zimmermann, Yoann Gasteuil, Mickael Bourgoin +3
We study the 6-dimensional dynamics -- position and orientation -- of a large sphere advected by a turbulent flow. The movement of the sphere is recorded with 2 high-speed cameras.…
