摘要：The low speed wind tunnel is more and more popular in civil applications nowadays.The aviation spray is one of the key technologies in agricultural aviation application while wind tunnels can create the right environment for aviation spray simulation tests.The authors collect and analyzes the typical low speed wind tunnel applications in aviation spray drift,droplet size distribution,spray prediction model building and droplet size spectra classification.The authors also put forward the suggestions of preferential domestic wind tunnel tests research not only for general agricultural aviation spray but also for the application of spray prediction model,spray with unmanned aerial vehicle and aviation electrostatic spray.
