Résumé
Time-resolved images of the resuspension of isolated micro particle mono-layers exposed to an accelerated airflow. Particles are bronze-made with a diameter in the range 20-30 µm. Airflow velocity at the center of the windtunnel accelerates from 0 to 9.0 m.s-1, with a fixed acceleration of 2.1 m.s-2 . Images are acquired using a CCD camera (SpeedSense 1020, Dantec) and an optical zoom x12 (LaVision) placed underneath the deposition surface, at a 30 Hz frequency. The field of view is 2.0x1.5 mm2 corresponding to a CCD sensor size of 2320x1728 pixels2 ; each pixel size is thus 0.86 µm. Each zipped folder corresponds to an independent dataset, from the start of the fan till the camera memory is full (2560 images).
