Spray Drift data from Flat fan and air Induction nozzles in IRSTEA Wind tunnel

These data correspond to sedimented deposition in IRSTEA wind tunnel for different types of nozzles (Flat Fan Albuz AXI and Air induction Albuz CVI 02 - 2.5 bar) at different heights (40 - 60 - 80 cm) and different wind speeds (2-4-7.5 m/s) Wind tunnel has a cross section of 2 x 3 x 9m (h x w x l) and sedimented droplets are collected on a distribution test bench (acc. ISO 5682) with grooves of 5cm width, 10 cm depth and 3m length. Deposition is weighted after a certain volume (Max capacity of filling tubes 500ml) or a certain time (ex 30 min). Each column gives the deposition value (expressed in relative flowrate) according to the settings inidicated on the first rows. The last row corresponds to the addition of deposition and provides the recovery rate on the distribution test bench. Sprayed liquid is water. 4 nozzles spaced 50 cm are set on a boom at the defined height and pressure. Input flowrate and pressure are controlled along the experiment. Wind speed is controlled with a 2D US anemometer, air temperature and humidity are controlled with ad hoc sensors and with the help of heating/cooling system.
