Experimental investigation of droplet impact behavior considering leaf curvature and vibration effects
This study clarifies the coupled roles of We, C<sup>*</sup>, and f in droplet-leaf interactions and suggests maintaining We < 132 in practical spraying. Under typical conditions, droplet impact velocity should be kept at 3-5 m/s, and reduced to 2-3 m/s for larger droplets (> 500 μm). To avoid resonance-induced splashing, airflow in air-assisted spraying should be controlled at 6-10 m/s. These findings provide guidance for improving pesticide deposition and optimizing spray practices.
