Abstract
Air-assisted spray technology can increase the droplet deposition rate and reduce droplet drift. In order to broaden the transport channel of droplets, the effect of wind speed on the dynamic change of static porosity of crop canopy was studied. Taking cotton as an example, we established four simulated cotton plants and measured the wind speed in the canopy. Through the numerical calculation of the windward area, airflow speed and leaf parameters, the change of leaf inclination in the stratified zoning is determined when the leaves are affected by different airflow speeds. Finally, numerical results of static porosity changes in different regions are obtained. The results show that the static porosity model can be used to calculate the dynamic porosity.
