Simultaneous 3D measurement of the translation and rotation of finite size particles and the flow field in a fully developed turbulent water flow [PDF]

, 2012
We report a novel experimental technique that measures simultaneously in three dimensions the trajectories, the translation, and the rotation of finite size inertial particles together with the turbulent flow.
