Wind Tunnel

The wind tunnel is just one of a handful in the world which can handle active ingredient pesticides and the only active one which can handle such sprays for simulated aerial application scenarios. It is used to measure droplet size for diverse spray types from agriculture to vector control, mining applications and waste water treatment, using three different laser measurement systems unique to UQ within Australia (a Phase Doppler, Sympatec laser diffraction and Oxford Laser imaging system). We use a different working section to also measure the drift potential of sprays to show the effects of changing nozzle, adjuvant or application conditions. The advantage of wind tunnels over field studies is that we can control the variables closely and contain the spray while sampling.

The wind tunnel is used to conduct studies for clients within and beyond Australia, particularly the U.S. and we are working closely with regulatory authorities and applicators/ registrants to help optimise the application of sprays to protect crops and human health while also protecting the environment. It is also a regular feature of our training courses for government aind industry with.
