Droplet spectra and high-speed wind tunnel evaluation of air induction nozzles

Qing TANG, Liping CHEN, Ruirui ZHANG, Min XU, Gang XU, Tongchuan YI, Bin ZHANG

Frontiers of Agricultural Science and Engineering 2018, Volume 5, Issue 4,   Pages 442-454 doi: 10.15302/J-FASE-2017169

Abstract:

A series of air induction nozzles were tested in a high-speed wind tunnel.The results indicated that v and v of the droplets decreased quasi-linearly with increased wind speed, while v was affected by the quadratic of wind speed. v , v and v of the droplets were all proportionalconsisting of droplets with a diameter below 100 mm (%<100 mm) was found to be quadratically related to wind
