We investigate the dynamics of very large particles freely advected in a turbulent von Kármán flow. Contrary to other experiments for which the particle dynamics is generally studied near the geometrical center of the flow, we track the particles i

International audience; Recent developments in time-resolved Particle Tracking Velocimetry (4D-PTV) consistently improved tracking accuracy and robustness. We propose a novel technique named "Lagrangian coherent predictor" to estimate particle positi

Protection localisée par flux d’air

Autor: Lionel Fiabane, Johan Carlier, Dominique Heitz

Publikováno v: Environnement.

La protection localisee d’ambiance par flux d'air consiste a preserver des elements de toute contamination aeroportee lorsque l’usage de barrieres solides n’est pas envisageable. La difficulte reside dans le maintien de la barriere contre la co
