Experimental analysis of PWM technology revealed its impact on droplet velocity and spectrum in spray nozzles, suggesting its potential for enhanced pesticide application.
Key Points
Pulse width modulation altered droplet size, generally reducing the volume median diameter compared to conventional systems.
The experiment showed that droplet velocity was slower with PWM, although higher duty cycles increased this parameter.
Flat fan nozzle types exhibited varying responses to PWM, affecting droplet size heterogeneity and spectrum.
Effects were evaluated under different operational conditions, confirming PWM's role in optimizing spray patterns.
